So, again, I saw lots of things I didn't realize existed before. I also met a lot of interesting people - Ken Tidwell was there as well as the English magazine and collectors scene lead by Mike Siggins. So - everybody will still have to play with 4 players. I played the cardgames completely and half a game of Elfen Wizards. I liked Rainbows very much, but didn't like Tricks.
Rainbows is a game of buying cards of different color and placing markers on a multi colored board.
The aim is to form colored rows with your markers. A nice card game, you need luck, but also some skill to master it. You select your cards in the first stage and then play a simple cardgame taking tricks. Maybe someone else can tell me whats good with it. There must be something, because many people bought it.
