I'm not a gamer at all so my answer will probably disappoint you lol. My favorite game is the sims and Northern Tales. I think they're both casual games and doesn't need much computer system requirements. I play Plants vs Zombies as well from time to time. I'm not serious about these games either, i just play them to pass the time.
At the moment I play Dragon Age origins, Baldure's Gate and League of Legends. There are some games like Sims, Evil Genius or Fallout that I start replaying every know and then too^^
Not much of a game person anymore these days. I used to be addicted to the various solitaire found on the PC and I downloaded candy crush at one point as well, but I got bored of them all now. I guess time is also just not available anymore with all that I have on my plate, but it is good to let your mane down from time to time and wallow a bit in fun.
I do not play play station WII or games like that. I like just mindless games. I love Zuma, but just the original one. I got hooked on it about 6 yrs ago and play it for a bit everyday. I also love Majohg, Freecell Soliltaire, and Spider Solitaire. I just go in and play them for a bit every day as a form of relaxation. Back when the original Nintendo came out,,, the one that had the cotrollers attaced with a cable and only had about 5 games on it,,,,, I did enjoy playing that one. We got one when we were living in Germany because there was not much tv available. My husband got it at the PX.
I used to play a variety of games when I was younger but I went into a gaming hiatus when I entered college because I needed to prioritize my studies. Now that I'm nearing graduation, I recently got back into playing computer games mostly because I bought a new gaming laptop. These days I'm usually LoL (League of Legends). I also play Skyrim from time to time but at this point in my life, I think that Moba games are the best for me because they don't take up a lot of my time compared to RPGs where you need to dedicate a lot of gaming hours just to finish and complete the entire game.
Most of the games I play are on the PS3/4. I play most of the call of duty games (MW2 being my favourite), I also play games like GTA V, resident evil games and the Evil Within. All of these games are highly addictive and they involve a lot of strategic work.
I play games more on my iPad or phone. I think it's easier than turning on a pc or Xbox. I do play on my Xbox too though. I like playing battlefield. I also play some games on the PS2 like SpongeBob: The movie game. I play this game for nostalgic reasons. I play games like Modern Combat 5 on my iPad. I'm glad I have the Veteran perk. I think people should give mobile games a try. It's way more complicated than PVZ or Angry birds. It's way better than that.
All of the Fate games. And Master of Orion 2 is still the best space game ever IMHO. Also EA sports 2008 Madden Football and Tiger Woods golf latest PC games before EA sports pulled out of the PC platform.
