That was awesome. I beat it in about 40 minutes. It was annoying to have my selection nullified when one of the constituent planets was taken over, and it was annoying to have to click twice just to send once, but the ability to send from several cells was very nice.
One of the things we want to do (or at least, this is the way I see it) with Dyson is to allow strategic players to succeed more, but still allow players who don't care about that to win by force of numbers (at least up to a point), and that's a really difficult thing to achieve. Allowing players more ways to send big swarms of units will really emphasize strength in numbers over strategic play, so we're still looking at this really.
Phage Wars is next in a long line of flash-based Galcon clones - it's definitely closer to Galcon than Dyson. I do like Armorgames though, they really get hold of the best flash gaming content. Thanks for the link!
