I got this game as part of this month's Humble Bundle, it seemed the most interesting part of it, having not heard of it before.

I played it a couple of times and was initially a little "meh" about it, but the more I played it the more I liked it. I like the interplanetary element of the game, it's rather interesting. And the game engine itself seems to handle thousands of moving units with little trouble.

I'm not any good at it, but I'm enjoying it

I played PA before Titans came out and it was a fun game. Any game that lets you fling moons about has something going for it!

Im pretty sure it's the spiritual descendant of Supreme Commander, in which large scale armies was a feature. I don't doubt PA can handle pretty big unit counts.
