Two other nice indie puzzle games he hasn't listed: Induction and Manifold Garden.

Of your engineering games, how would you rank them by order of preference? What about by difficulty?

Ah, that's good.

For some reason I've never really been able to get into engineering games very much. I recall that when I played SpaceChem, I ran up against a brick wall when I got to that one boss you need to defeat with a uranium cannon. (This was ages ago when I played it, so maybe I'll give it another shot?) It seems that all engineering games I play (even those that aren't yours), there's a difficulty wall of some sort...

Also, I really liked the concept of KOHCTPYKTOP. Bit of a shame that got out of my league fast too. And Codex of Alchemical Engineering was nice, though that again seems to have thrown me a difficulty wall a few levels in.

Still, fingers crossed that Opus Magnum won't have the same problem.
