Basically followed the progression zvrabes mentions - bashing that saucer and the show when you blow it up just feels great, and I eventually worked my way up to TA. Inifinitely repayable - spent hours playing over and over again with casuals. The one game I know of with a 100% hit rate.

This is the platonic ideal of a pinball machine. The casual loves to bash a saucer. The intermediate player yearns for Total Annihilation. The advanced player is lured back to a game they thought they'd figured out with the promise of the 1 billion point hurry-up. And the experts will agree that getting to Rule The Universe is one of the most difficult and rewarding wizard modes. Set it up steep and tight and watch people get hooked on pinball.
