Thanks lempkee,
I have heard good stuff about forematt before. And brought my original Quake from there (for £10). I noticed though that Quake 2 costed £30. ARGH! I noticed a PC version of Quake 2 in a second hand shop for £2! I was gonna get that but i couldn't find an engine for it on the Amiga, so i didn't bother. Pity!
