I played some TA in my time and recently stumbled upon replays on youtube. There is some way to play the single-player experience online already though a bit shady on the copyright it seems.

The original game got a lot of things right, I saw videos of Beyond All Reason and while I didn't play it it didn't quite _feel_ like it would give the same feedback while playing.

I was considering doing exactly that in my spare time, so thank you nanolathe I'll definitely check it out.
