Zerospace: RTS/RPG mash up now on Kickstarter

This ambitious RTS/RPG mash-up from Starcraft pro players draws inspiration from 'games like Mass Effect or Baldur's Gate,' and it's on Kickstarter now

I would love more command & conquer games. There hasn't been anything new in a long time that has that feeling of collecting resources and building bases and troops.
There's also Stormgate coming out later this year from a load of the former StarCraft developers.
i have a feeling that if there is going to be a good rts in the next few years its going to either stormgate or zerospace
BAR might scratch your itch. It's also free and open source
BAR is really more close to supreme commander to the point that when i first saw it i was thinking "wait what they made a new supreme commander"
Others have mentioned Stormgate, but I think the upcoming Tempest Rising is more in the Command & Conquer vein
I'll check it out :)
