The best game I played at GenCon 2010, and from the hype and the description, I was actually expecting to be lukewarm at best about it. Very solid drafting mechanics, very quick play, accommodates a larger than average number of players, and asymmetrical starting boards.
A rule of thumb as you look down the list of comments: in virtually every comment that says it is "random" "chaotic" "luck driven" or "low interaction", you should replace those statements with "this person doesn't know how to draft".
it does exactly what it's supposed to do, which is help kids with colors (even though it's more of an "activity" than a "game", in the technical sense). i'm tempted to give it a 10 for the deluxe version
Yup, it's Ra. If you already own Ra, you probably don't need to spend the money to get this. If you don't own Ra, I'd buy this version.
It is more visually appealing than Ra, and you're making slightly more worthwhile choices, and the scoring system is better; however they aren't grand sweepingly awesome changes, they are only mild tweaks. they also make teaching the game a teensy bit harder, and they make the playtime a teensy bit longer.
