Best game of all time? Newbie

[JoyBoy]

I recommend the following games from my near 23 years of gaming

Speccy - The Great Escape. Never did manage to escape mind you. Everytime I did, I was captured again. Was it even possible to escape without being caught?
C64 - There can be only one. IK+
Master Syetem - Alex Kidd in Miracle World. Although, Sonic 2 could tie it first. Actually so could Grand Prix. Hous of enjoyment out of that little racing game due to being able to make your own tracks!
Mega Drive - Too numerous to mention. Sonics, Streets of Rage, Street Fighter, Rock n Roll Racing, Speedball 2, Sensible Soccer, the original FIFA Soccer, EA/NHLPA Hockey. The list could go on and on. Loved this machine!
Playstation - Gran Turismo 2, Metal Gear Solid and Final Fantasy 8.
SNES - Super Mario Kart.
GBA - Super Mario Kart.
PS2 - GTA3, Vice City, Resident Evil 4 and Gran Turismo 3. GT4 just didnt feel right.
360 - Bioshock, COD4MP, The Orange Box (all of it, if anything TF2 lets it down due to getting no support from Valve ) UT3 gets a mention as well, simply for being Unreal. Facing Worlds is perfect.
PC - Half-Life, Op4, Team Fortress Classic, Mafia and Deus EX

Overall, I gotta say the best game ever, ever, ever is, well, I dont know! If pushed, I would say Half-Life for SP and TFC for MP
