Savage Worlds is pretty awesome. Its inherantly pulpy, but most things that you'd want to turn into a game are pretty pulpy anyway, so it works for lots of stuff. Playing in a short run game now where the PCs are all monsters, working for the Dark Lord of Darkness. We take on missions like 'bring me the head of the bishop in town' and 'kill this adventuring party but bring me their elves alive'.
The damage system is a little overcomplicated for my taste, but the rest of the system makes up for it. There's a few basic kinds of spells for instance, but you customize them with your Trappings. My mummy wizard for instance melts people's faces with black necrotic energy, while the Huckster I played in Deadlands would flip his deck of cards, cutting into the target like razorblades. Both are the Bolt spell with different trappings. And these do matter beyond flavor - someone with resistance to Dark Magics might be immune to the Mummy's blast for instance, while the cards would work just fine.
Huckster was neat, I had some good trappings for him. He would deal someone a card from the bottom of the deck to boost or lower their stats, or lean down to a wounded ally and pull an ace from their sleeve to heal them.
Fun fast game that's adaptable to a lot of settings. Among my plans are a sci-fi game, a zombie outbreak, and I want to use it for a WW2 game using green army men as minis.
For the subject, I would love to play Godlike. WW2, the Allies are nearing victory when beings calling themselves the Norse Gods appear on the battlefield on the side of the Axis. It is only because a single god, Loki, appears that the day is not lost. Soldiers begin developing new powers, and the war rages, with the PCs playing super-powered WW2 fighting Joes.
