I can't see ever paying the 40 points. If I want to play a game so badly after the demo trial that I'm willing to pay $0.50 for a game, I would just as soon pay $3 to own it.
I bought Scramble and Tempest and like them both. Not much else for me in the first 2 packs. The racing game (Road Warrior?) is fun, but not enough to purchase. I'm a big Super Cobra fan, but the emulation felt way off. And I can't see paying $3 for any Atari or INTV title in the game room. Arcade all the way!
