Warband is fun. Sort of a cross between Total War
and Sid Meier's Pirates!
. Go around, building up fame and fortune, fighting bandits and then eventually taking on the armies of other nations. Act as a vassal to your liege and be rewarded with castles and towns or eventually strike out to try and forge your own kingdom. Hire on NPCs who'll enhance your party's skills (medic, tracking, sieges, etc) and have some RPG-style interaction with them. A bit of repetitive stuff (kill enemies, find town to sell your swag at, buy food, rinse & repeat) but still a lot to do so it's not a mechanical grind. Combat is sort of like Total War in troop movement but you also control your character directly and can ride into the melee, slashing at peasant archers or enemy knights in a FPS style while your troops battle around you. There's a multiplayer mode which is just battles without all the single player RPG character development and nation builder elements.
It's rough in that the graphics look like something from the early 2000's and some of the interaction feels limited by modern standards. It's sort of amusing that you have as many sliders when making your character as you see for Skyrim or DA:O but no matter what you'll still look like someone carved you out of a potato
If you can get past the "This is a not a AAA title from a big developer" hump, I think you'll like it if the above sounded interesting.
