Very cool game. I've only played the introductory card mix so far, but it has a lot of promise. UPDATE (Jan. '10): Now that I've had a chance to play through all the cards, I'm going to say that this game lives up to the hype. It doesn't beat Race for the Galaxy, but it's much easier to teach to new gamers.
It's hard to know how to rate this one. I'd rate the solo-play at around a 7--it's fun, but not how I'd prefer to play the game. The new cards and homeworld are great-they just add more to a game I already love, so that gets a 10. I haven't tried the goal cards yet, so that may change my final rating, but I think I'll give it a 9 for now.
Fantastic! Simple and quick to explain and play, but the race/power combos give lots of replayability. I'll definitely bring this out for the Carcassonne/Settlers crowd, to give them a taste of something new.
One play so far, but we're still working our way through the rules. UPDATE (May '09): Played with all the rules now, and it's a very interesting and subtle game. I can see why so many people are crazy about it. UPDATE (April '10): I've joined the Tichu cult. It's going up to a 9. Perhaps my favourite 'classic style' card game.
