Heres another idea.
Putting the popular game Risk and Bounding together to make a fun game.
But for my idea of risk I was thinking something like splitting the races of Sc instead of everyone having the same units.
Like

North + South America = Terran
Africa + Australia = Zerg
Europe + Asia = Protoss

And having the defense go with the race like.

North + South America = Bunker + 2 Rines [6 Damage] <-- Shortest Range
Africa + Australia = Sunken [5 Damage]
Europe + Asia = Photon Cannon [5 Damage]

And like have a chain Terran > Zerg > Protoss > Terran
Something like that.
And for the bounding part, you would bound to gain your minerals. And there will be a timer.
To make the bounding a little bit spicier, when the timer goes down to 0, then the obstacle changes.
Also, you can set your own intervals ( Set Timer ) inbetween each obstacle.

I kind of like the original RISK better than that. Cards FTW!!!

name it bound risk and to get a unit or move you would have to bound an ob
