Infinite resources.
This game is meant to take time to beat. You should not win it in one sitting! I hope that you don't. ^_^
There is a lot here, and you may not need it all to be victorious.
The game is intended to be more about the experience rather than trying to win. So please guys, take your time, explore the game, try different things. It isn't a race to beat it, just try to have a good time getting your troops killed.
