Well first I'll start with talk of WoW and EQ2 since they are more on par with eachother. That and I was in the WoW Stress Test and am currently in beta for EQ2.
Of the two games, I like WoW MUCH better. EQ2's graphics are FAR more realistic compared to WoW, but EQ2 lacks the soul and spirit that WoW has(also, WoW isn't going for a "realistic" look). Of them WoW is just a lot more fun, forgiving and easy to play and learn. Of the interfaces I like WoW better too. EQ2 takes a "Windows" menu style approach and even has BLACK BARS along the top and bottom of the screen kind of like playing a Widescreen movie on a fullscreen TV(taking up about 25% of your screen)!! WoW fills your full screen with the interface taking up minor areas. EQ2 keeps zones while WoW has no zones no matter where you go. No more "Loading, please wait...." I can't tell you how much nicer it is to just go anywhere you want without loading screens. WoW also gets you in the game MUCH faster, taking maybe 20-25 seconds compared to EQ's minute and a half plus(Not actually timed, just how it feels, WoW is FAST though).
Lastly I don't really want to give SOE any more money. I played EQ for most of the 5 years and it was a grind most of the time. If I sound jaded, it's because I am, but if EQ2 were something to make me take back those feelings I gladly would, but sadly can't. It's still a lot further from finished though and unless I can get back in WoW I'll be playing EQ2 on and off. Blizzard on the other-hand has a rep for making great games and this one is right there with the best. I do concider WoW better than any MMORPG I've played(having played Ultima Online, Anarcy Online, DAoC, EQ, EQ2-beta, Matrix Online-beta, WoW- stress test beta).
Stress test I played the Hunter class and enjoyed it greatly. I reached level 17. I'm sure I could have hit 20, but because I knew my time was limited I wanted to explore and see if there were good places off the beaten trail to level, and I wanted to see the other lands. I wanted to best take advantage of my play-time so that when the game goes live I have at least some edge on the masses of players that will all be in the same areas.
Sadly the areas are designed in such a way that everyone will pretty much be in all the same areas at the same levels. What is a good idea though is that when you're running low on quests or they're just getting too hard, you can go to other race's areas(of your own team) and do quests there. Quests are by far the better ways to gain exp. Some people grind but that's boring. Quests tend to give reasonable items, experience and cash at any given point.
**The above is also a cut and paste from the "Open Beta" thread I originally post it in but felt it applied here.**
As far as the original Everquest....
Leveling: WoW is meant to level much faster. A casual gamer should get to the level cap of 60 in just a few months(talking about playing 2-3 hours a day say 4-5 days a week). Hardcore power-gamer could probably cap in 1-2 weeks(10+hours play a day). WoW is geared to the casual gamer.
*How does this differ from EQ? Leveling in EQ is a grind. In EQ expect to gain all your experience from killing creatures and THAT's it. WoW gives a LOT of experience from quests, in fact your best experience comes from quests. This makes you explore different areas and makes leveling MUCH less of a chore. Lastly, DOWNTIME between fights is a LOT less than EQ, in short that means more fun and less boredom.
Classes and grouping: There is still work being done on the classes, many talents and abilities are not finished. As far as what I am hearing about the high-end game, Priests(Clerics) are not NEEDED! Yes, they help, but you can do without them almost as easily. EQ you really MUST have a cleric or ClericS. Enchanters in EQ are near a must in many areas too. WoW is a lot more forgiving. I really can't comment on this end of the game but HAVE been reading the lvl 55 players comments and so far it sounds a lot nicer than the EQ situation.
Tradeskills: Well, there is old EQ way, new EQ way and the WoW way. You know how EQ works so I won't bother with talking about that. WoW is nicer in my opinion. I don't know if it will be live the way it was in the stress test, but when I did it, I never failed a combine(this could be because a) they wanted you to gain quickly for the sake of the test(doubting this as being the case), or b) because the items and skills are LEVEL BASED(meaning you must be a certain skill level and/or character level before you can learn a given item so if it is in your range or lower you can make the item without fail. As I said, not certain if it will go live that way)
Anyway one nice thing is they give clean menus and show you how many of an item you can make based on the tradeskill items you are holding. Anything you make is "stamped" with your name (Made by "player-name") which is really nice.
You are limited to TWO major professions but may have all three of the minor crafts. The reason I think this is good is it promotes diversity. You won't have level 1 characters who are maxed in ALL the tradeskills, nor someone of any level with them all. Because of the level restrictions you would have to have multiple characters of capped or near capped levels to have all the skills and THEN because of specializations you'd need to duplicate tradeskills. What I mean is that at the highest level of Leather crafting you must pick one of 3 areas to specialize in. If you want to do the other two areas you need two other characters to do it with. Blacksmithing breaks into Weaponsmith and Armorsmith at it's highest levels. This adds more depth to the skills AND diversity. What I also like are the "Collection" based skills Skinning, Mining, and Herbalism. Those just collect things needed for other tradeskills. Most people will pair a collection skill with a creating skill, others might just have 2 collection skills just for the income it will yield. Either way there are a lot of cool options. I think these approaches offer more opportunities to players. Oh, if I didn't mention it and I'm sure I didn't, many of the higher end recipes are drops, none of them are "automatically" given to you just because you have the skill to make and item. That means you will have to either get the recipe yourself or trade/buy/auction for it from players who have it.
Closing: It's not my intention to tell you what to do or even direct you. I think WoW is honestly the better game. If not for you, then for ME. I have a wife, 3 year old daughter and a full time job. I don't have the kind of time to play as when I had first started EQ. Even when I had all the time I wanted to play Everquest, I have to say it was WORK. There was a LOT of boredom waiting for health or mana to regen. MY GOD, they created a GAME to play just to help you pass time until you could play again!! /gems if I'm not mistaken. What made EQ fun? Mostly it was the people. Yes, EQ lasted on more than just that, but it really became a job. WoW is FUN. It's geared to be faster paced. You can play PvP if you want or not(PvP server which is fulltime PvP-teams or regular server which is PvP part-time(as in PvP when you want to, not when someone else feels like making you)) I want to have fun with or without people. I'll still play with groups and be in a guild if not start a casual guild, but EVERY CLASS CAN SOLO AT ANY LEVEL, granted there is content that can't be soloed but that should be expected. Also, expect WoW levels to hit 100+ eventually, and not 5 years later! Raid content is currently being added and expanded on as well as the full PvP rewards system.
I'm personally done with EQ. I think a lot of people playing EQ are only playing until something better finally comes along. WoW is IT for me. I played a class that was last to be added, still lacked a lot of things like talents and other finishing touches and I liked it better than anything in EQ already. Enough said, peace. may you find what you are looking for in a game if you haven't already. Mine will be here when WoW ships.
