CrazyAdmin has created an online text based RPG for the PSP. He says “It allows users to attack each other or monster to train (on). It's only for Psp's with 2.0 firmware, because I don't believe the wipeout browser supports php. The rpg is browser based and fits perfectly to the psp on any browser display mode.” This reminds me of old BBS door games. Please don’t kill me =(
