finally a game where you learn something.

Build things!!!!!!!!!!!!!!!!!!

and experience the usefulness of an engineering degree!

Ages ago there was a cool little game called Pontifex. This is an update of the same idea, using different materials to build bridges with varying difficulty. It's nicely enough done although compared with versions 1 and 2, I don't like that it seems to have lost the visual stress indication when running the simulation. If it's not lost, I can't see how to turn it back on.

On the subject of versions 1 and 2, I got them all 3 in a decently discounted bundle: I suspect I'd be a good deal less keen on version 3 if I'd paid full price for the others. Version 2 seems a bit nicer than version 1 and version 3 works well enough and seems to have some more stuff like weekly challenges. But really, there's not enough difference to justify 3 versions. This is the Dovetail Games marketing model where you buy the same game repeatedly and it doesn't do the devs/publisher much credit in my opinion. If what you've written is an update, then it should be sold as such not a whole new game.

That said it's engaging and fun and I will likely keep it. For me, it's something to get when it's on sale, though. Especially if you already have either of the earlier versions.
