[quote name='sidochrome']While I didn't plan on picking up Catan, the generous demo is rather enticing.
Is Carcassoine very different to Catan, and as such, worth holding out for over and above Catan? I'd never played either board game, and I'm curious.[/QUOTE]
I like Caracassone a lot better, but both are good games.
The outcome in Catan is more based on luck, because of dice and card draws, which is why I don't like it as much.
Caracassone is a tile laying game. You have a big stack of face down tiles, and each person takes a turn picking and placing one. They have to match certain things on the tiles with what's laid out, and then players can place little guys on the tiles for points, and try to grow the points with more tiles.
If you have an extra $20, go buy Caracassone: Hunters and Gatherers and play it with your friends. Lots of fun.
