Two victories:
1. After Amazon's one-day shipping messed up my order, we had to go searching for Gamma World in realspace, and ended up finding a gaming/hobby place we'd never known of that is much closer to where we live than Games Workshop, and does CCG, RPGs, anime, manga, tabletop... everything a geek could want. Very cool discovery, and they had Gamma World.
2. Later came playing Gamma World with DreamGoddess and my twin 8-year-old cousins. They grasped how to play pretty quickly after I'd simplified the stats and numbers, and hopped happily aboard imagining themselves as a Timeline-shifting Android in a suit of dead rabbits with a bunny-shooting bazooka, and a toxic rock-man wearing tentacles who reaches into a dimension of pure octopi to throw them at people or whack them on the head. As we went into a second session the next day, I was able to introduce a couple more of the rules (changing their stats some) although I toned down my penchant for darkness in scenarios, opting for a traditional monster hunt and then a protection and rescue. These two sessions were my first time playing this kind of game in real life as opposed to over the internet and it presented its own interesting set of challenges and rewards.
But the awesomeness is that we all had fun and my cousins are already asking to play again soon. Fresh recruits!
