Lol im pretty sure the main things we did on it (me and my bro) was playing Lemmings, The Settlers and Pengu. There the only games i remember playing.
I believe my dad used to own a Sinclair ZX81 too, and apparently dabbled in game making, and thats even more unbelievable, considering he's only held a PS1/2/3 controller about five times in his life, an Xbox 360 controller about once, and a Wii controller a few times. He's never played the SNES, N64 or GCN, or the original Xbox. Strangely he's played the PS1, PS2 and PS3.
