Quicksilver is a sweet game.
I've never played a cheetah but the layout looks great.
Lightning is fun and challenging but good luck finding one with nice artwork.
Meteor set up correctly is great.
Iron maiden is a treat to play if you can find one.
Catacomb is fun during game play but the BG game kills it for me. Stops the game to much. It's beautiful and a fun shooter though.
Stars can be brutally simple.
Everyone wants a stargazer.
Viper is interesting with its turret gameplay. Jury is still out for me on this one.
Galaxy I'd decent. IT needs to be setup hard though. Think of it as a more new player friendly meteor.
