Virtual Pool Mobile, probably the most spectacular billiard game for the Pocket PC, has just been updated to support WM5, VGA and, what is more, the Intel 2700g graphics co-processor in the Dell Axim x50v/x51v.
I've tested the game on the latter (an x51v). It's indeed spectacular and has almost no 3D rendering-related bugs. The trial version of the game is indeed worth a try if you have an x50v/x51v.
Too bad there's no multiplayer in the game at all - that's the only thing really missing from it. That is, if you want to play friends, you need to go for either
Mobirate Billiard Master 2 or
i-mate Pool Multiplayer. Please see
The Definitive Multiplayer PPC Game Roundup for a review of these two games.
