This ideas been bouncing around in my head for a while, I'm not likely to do anything about it anytime soon, so I thought if post it here and kick it around for a bit. See if anyone has any thoughts on the mechanic. If you haven't played dominion the central mechanic plays like this. The game comes with twenty five cards. Each game only uses ten cards. All players have equal access to the cards, and the game comes down to who can make the best use of the cards available. Plus a small amount of luck. My thought was applying this to an RTS. The game comes with a massive tech tree. But in any given round only 20% of the tree is available. Gameplay would focus on choosing the best combo of units available based on the tech tree. Thoughts?
