Hi,
I wouldn't bother attempting to run OpenTTD on a 68K - on my 68060-based A3K, it crawls along...
Shame really as it's such a cool game! Some things just need PCs!

EDIT: annoying really, as the original assembly language-based TT and TTD ran fine on slow 486s (25MHz was fine!) but the portable C-based OpenTTD just has too much of an overhead. Anyone fancy coding a native Amiga 680x0 asm version?! :-D
