I honestly don't care if a game has a system borrowed from another game or not. I see no point in judging a video game based on that kind of criteria. Maybe its just me, I dont know, but I judge a game based off how much I enjoy playing it. If I dont enjoy it, I dont play it. Some games use the same mechanics as others, some innovate with all new ways of playing. What matters is that time spent playing is fun or frustrating.
If someone else enjoys something I dont, it honestly doesnt bother me. I have enough in life to worry about besides some dude's opinion of a video game that I may or may not like. There's really no need to get into a 4chan /v/ style internet fight about who enjoys eating sh*t more than the other. Haters gonna hate.
Still, I'll never understand the drive behind someone who legitimately hates a game hanging around a forum whose topic of discussion is centered around said game just to post about how much they hate it. If this were a general video games forum I might see why. I just dont see a point in wasting my time like that when I could be doing something I enjoy.
