Another recommendation!

[Ersatz Nihilist]

I just wanted to stick my head round the door and leave another recommendation for this game and urge people on the fence to take the plunge, especially if you're looking at it in the bargainous Steam sale - at the very least download the demo and spend a bit of time with it!

A Valley Without Wind is pretty indimidating at first, but as you'd expect taking time to read the tooltips makes it much clearer - Like AI War there's a huge amount of subtlety and depth here that you can play for hours without seeing. I spent a fair old while with the demo before purchasing the 4-Pack to hand off to friends; not sure how multiplayer will work but if you can have everyone off working on their own things and coming together for the big challenges it'll be dead good.

So anyway, cheers Arcen guys - if you keep producing (and very importantly supporting) software like this, I'll keep buying it.
