I can’t say that I’m really into keitai gaming — I pretty much limited my gaming to Solitaire, which stopped as soon as I got my DS, and then my PSP. But Paul over at In-Duce is really into mobile gaming, especially when it comes to networking and GPS-related functions. He gives us the lowdown on the gaming scene on the very popular WIN phones (I have a W21S, which is the same phone he had, until he recently upgraded to the W31S).
