I play Starcraft II for the strategy games. I also played a lot Neverwinter night (during 5 years, in a roleplay server), mass effect, dragon age, but also games as Splinter Cell, Wow, Gears of war... I am not really sectarian =]
Nop, I never played at Devil Survivor... I don't very like tactical RPG (I played a long time ago Final Fantasy tactics, but no more). If I can advise you a game i very liked: Machinarium from Amanita Design, a little studio of Czech Republic. It is a adventure point and click game, quite short, but very nice, artistic, and clever =)
By the way, I tried to post a new thread with my questionnaire for my university study, you know why it is not online ? Maybe I have to wait some time or something ?
