I already own GC2, without a Steam key. The box for it is on my DVD rack next to the reason I don't give EA money.
I've also already played Rebel Galaxy.
OWTC is one I've looked at in the past, but it doesn't include the $25 worth of game DLC, so while the bundle might be a good deal overall, that would be $40 inclusive, which is more than I'm going to spend right now. Especially so since I'm currently back to modded MC.
