Which one is better? I heard that the ones that stick on the PSP screen isnt that good. So anyone can recommend me one? And does anyone have the crystal casing for the PSP? Mind telling me if its a good protectiong unit for it? My Aunt it going to Australia next week and i want her to get me one. Thankz in advance. Also what RPG would you guys recomend? I prefer RPGs over other genres.
