Back in the day I had an 040/33. Transport Tycoon is, personally, one of the best games ever made, and I could never actually play it on my Amiga. That stuck with me for an embarrassingly long time.

So I fixed it. I've ported OpenTTD 1.0.5 to classic AmigaOS on 68k, and it's playable on 030+fpu.

https://github.com/angree/openttd_amiga_68k/releases/tag/v0.3

You can run it in lores (including an overscan mode) when you want speed, or in hires interlaced AGA when you want it to look right. The interface font follows the resolution so the lores modes are actually usable rather than a squashed mess, although windows need some moving sometimes. Picasso96/RTG support is coming - the driver is structured for it - and right now I'm working on sound.

There is an older OpenTTD floating around for 68k, but from what people say it was never really stable and it's pretty outdated. This is a fresh port with its own native video driver rather than anything SDL-based.

Is creating this in 2026 slightly absurd? Yes.

I just wanted one of my favourite games running on my favourite platform, and now it does.

(edit) Minimum specs: AGA, 16MB RAM, 68030+FPU

Recommended specs: AGA, 32MB RAM, 68060/68080 cpu

Surely you mean 'MB RAM'? =)
