Ive got a collection of just over 100 megadrive games. And about 6 or 7 megadrive console box variants. Also got a stack of master system/n64/ps1 gear.
As for PC I have an athlon 1600+ with 256mb ram and a geforce 4, running windows 98se! Really dont use it that much tho as I had to start concentrating on baby stuff and didnt get many games.
