If you want to see/critic a game(s) then you have to first look @ what type of games they are.
Broadly you will find:
First Person Shooter (FPS) - Quake series, Unreal ,doom
|_ Space Simulation - Descent, Star Lancer
|_ Flight - M\\$ Flight Simulator, F22 Raptor, F16 etc; Commanche Series
|_ Car/Drive - NFS
|_ Dungeon Siege
|_ Tekken series, Mortal Kombat
Scroll Games also RPG:
|_ Age of Kings/Empires, Command && Conquer series, Simcity, Caesar, Diablo
|_ Tomb Raider, Indiana Jones
@ one estimate you might be having more than 10 -20 genres today. So go ahead and work about with the history of games. Today's games - well you will get lotsa help - but I guess you should first look @ the games that started it all - Mario, Contra etc; Then come to the Classic Doom, Wolfenstein. Then you might end up with the today's gamez.
I think you will have a balanced act with:
StartX: Mario -
New Ideas: Doom
AI: Deus Ex/Max Payne/Half Life/ Thief - order of precedence Thief being best @ AI (IMHO)
