Like all things gaming related, and RPG related, what defines a good system to one nerd defines crap to another 🙂
I played savage worlds for a bit. Ran a small Gamma World adventure, and played in some weird war games. Also a Fantasy game. The mechanics are pretty easy. Game play is fast. Though I will say in the end it felt a bit "empty" to me. Also, the exploding die mechanic as RAW can get pretty out of hand. This was all a while back, so not sure if they have revamped the rules at all since then.
