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.
Just Cause and Dead Rising are known, but not well known
You're joking, right?
Age of Empires definitily
Okay, why do so many people think this game isn't well known? If you're all saying it, chances are, it's not that secret.
Timesplitters! I can't believe not many people have heard of this game
Fairly well known. 2 is my favorite.
The Age of Empires Series is awesome...sadly not too many I know even heard of it.
Again, are you kidding me?
From old games - Fallout 1 and 2, Starcraft, Lands of Lore (i like this one), Ultima 7, Doom 1, Doom 2, Heretic, Heroes of might and magic 3, Diablo 1, TA Kingdoms, Age of Empires 1 and 2....
From new games - Doom 3, Heroes of Might and magic 5 (those 2 are relly good ones), Worms, Diablo 2, Unreal tournament 2003, Flatout 2, Oblivion 4, Red alert 1,2,3 and Demoigod
I repeat, UNKNOWN GAMES!
My favorite is probably Extreme-G. Played it when I was little, and haven't heard much of it since. That was a great game.
