Indeed, Catan is quite fun.
And then, speaking of CCG's, there's another game I've just been getting into:
MONSTERPOCALYPSE.
The collectible minis game of B-movie Kaiju city-stomping.
Pick your monster - will it be one of the heroic defender robots of GUARD, the mysterious biomechanoids of the Shadow Sun Syndicate, the Gojira-alike Terrasaurs, the Martian Menace, the terrifying Planet Eaters, or the mind-shattering Lords of Cthul?
Line up a few 'popcorn' infinitely-respawning units, like tanks, helicopters, ninja, dinosaurs, flying saucers, or brain-eating alien worms...
And set up a few buildings to knock down.
Then sit back and watch the action, and try to vape your opponent's monster before he can vape yours.
Pick tanks up and chuck them through buildings. Body-slam monsters. Combine several units' fire for massive attacks to turn the nuclear power plant he's hiding behind into a radioactive wasteland.
Blow. Stuff. Up.
Coming soon is set 2: I Chomp New York.
