The earliest games i can remember playing were Sonic and Knuckles, some game on the commodore 64 where i was apparently hunting jack the ripper in a waxwork museum.
Then there was Dynamite Heady on the Megadrive which i still have today and after that my Playstation with a ton of classic platformers (like Crash, Spyro and Gex) RPGs (FF 7,8,9. Digimon world 2003) and Tombi
Handheld my childhood gaming belonged to Warioworld 2: The quest for the golden coins, the first game i ever 100% completed. every treasure, alternate quest-path the lot.
After that it went Gamecube, Wii, Xbox 360 and i'm all grown up. damn, there is of course games like Pokemon, Tetris and Point Blank....too many to remember.
