Nominate Race to 1500 for Best General Mish Mash game.
The primary reason is the game's popularity; not only have over 100 games been played in that one thread, but I think it also has one of the highest (if not the highest) page counts in all of mish mash. That's really says something about the game. Furthermore, the host (mallowgeno) has been very active and done a great job of maintaining the game. Aside from that, I like the simplicity of the concept, and I also find the game fun.
