Sure, you hear about Halo, Call of Duty, Fallout, etc. But have you played any good games that aren't popular/are underrated? For me, I would say Katamari or Civilization 4.
I haven't met many people who know of Neverwinter Nights actually
Ive heard of new winter nights it amazing. I dont think many people have heard of bualders gate from the creaters of new winter nights its even better.
I used to play some really old games like "Space Invaders" and a few of the old Sonic games. I even have this CD that has a ton of old games like "Shining Force", "Kid Chameleon", "Vectorman" and "Comix Zone". Ah the good old games... Can sometimes be the best.
