I"m split. for shooters and the like, half-life 1 takes the cake. first true AI, great SP story, and still #1 in multiplayer (more than 20k players approx, HL2 is second with a few 100 or so less, BF2 is below that, then come Wolfenstien: Enemy Teritory the best free WW2 shoter EVER!) for consoles, etc, super mario world. first mario game to allow you to revisit levels, easy at th ebeginning, hard at th end, overall wonderful. that's just my 2 cents.
