For YEARS it was GTA San Andreas. GTA V/Online has probably taken the top spot and is also my most played game at the moment.
Mass Effect I liked, but I hate EA and their policy of chopping a game into small pieces and selling you the pieces at inflated prices. As a result I held off on Mass Effect 2 waiting for a GOTY on the 360, and the 360 never got one (the PS3 and PC did) so I decided fine, the story ended with the first game. Screw EA.
Yeah, I really enjoyed the Mass Effect trilogy. I'm looking forward to Andromeda as well. I liked the Witcher a lot as well. BioShock trilogy is another good one. I have spent several hundred hours playing Civ V, so I guess I like that game, too.
don't know man that's pretty hard I guess I would have to say the Mass Effect series I mean together they give you a pretty good amount of stuff, exploration, side quests a good story line, combat, open world etc, etc. I agree though that ending blew hard... but I have hopes for the next mass effect game.
I'm still a sucker for the Kingdom Hearts series. Loved Kingdom Hearts 2, as a kid I was convinced that Sora and Kiri were going to kiss and I was psyched lol. I think I looked forward to those two locking lips more than my first kiss lol! Sadly they never did
