Pokemon would consume me for hours beyond end, and I only ever had Pokemon Red.
Fallout 3 is amazing to me when talking about current games.
For
PC series, I loved Red Alert or any of the Command and Conquer games.
For online games, I loved the MMORPG Maple Story, and spent around 3 years playing it.
Anything Mario is pretty fly. My favourite would have to be Super Mario 64 though. Super Mario World on SNES was pretty crazy tooo.
N64 has to be my favourite system of em' all though. Banjo-Kazooie, Perfect Dark, Mario games, Donkey Kong 64, Golden Eye. All too good :]
