A half-decent RTS for Android

I recently found an in development RTS for Android called ProjectY. It's by far the best RTS I've seen on Android but it still needs a lot of work since you currently can't build structures and it works more like a real time tactics game. Anyway, it's worth checking out and hopefully it will get to the point where it will be a great RTS for on the go. Here's the Play store link and site link. Also, the site says iOS and Windows phone versions are coming soon.

(I know this is a little unrelated but I figured other PA/RTS fans would like to know about this game for an on the go/quick RTS fix.)

I prefer Z Origins for my android, but mostly out of nostalgia

Tried this game, and found to be really bloody slow.

Not really regarding PA - moving to unrelated.

Is it completely free? In-game payments? Donation-supported?

Free with the option to buy more maps.

Hm. Interesting. Is there multiplayer?

I'm still firmly in the camp of 'pay up-front for the full game' but I understand that isn't usually very effective for the mobile market. I'm certainly interested by this.

hm, that looks quite good. I may have to look into it.

Yes, but I haven't tried it out yet. I've only played a few games against the AI to get the feel of it.
