Haven't seen RBI Baseball mentioned yet...used to play it for hours and hours as a kid Tecmo Super Bowl Double Dragon Ninja Gaiden Castlevania Bases Loaded Mike Tyson's Punch Out Rad Racer Mega Man
I played almost all the ones mentioned in this thread.. but the two that were most memorable when I was a kid: Ultima 4 Ultima 5
I played the Conquerors edition of this. Pretty much the same just the expansion pack. Only computer game I ever played with the exception of Starcraft (didn't like this as much). I was a God in Super Smash Brothers, Halo, and Soul Calibur II. Top ranked in the world / high school. Other games I loved playing were Call of Duty Modern Warfare 2. All the Maddens up until 2012. NBA 2K6-9. Star Fox. There was this tank game on N64 I liked, and this Aces High (or something like that) fighter plane game I loved - this was for the PS2. Assassins Creed was fun. Tekken. Power Stone War on Sega Dreamcast was fun which I am sure not many people will know.
Haha that was a fun game. If you laid down like a dozen mines and then rolled your tank over it, the game would freeze every time. Or at least, my friend's cartridge would do that. We did it frequently and it was always funny (to stupid kids). An explosion, the screen would shake, and then it'd freeze.
Zelda ocarina of time, Goldeneye 007, Mortal Kombat, Super Mario 64, Super Mario World, and Pokemon red/blue.
Holy crap I completely forgot about that game. I can't even begin to imagine the amount of hours I spent playing that game.
