Sorry if this has been answered elsewhere,but I couldn't find anything on the forums. If I download the PSP version of this game from the store, and then later decide I actually want to play it on the PS3 instead, do I have to buy it again, or does the single purchase allow me to download to either platform?
On XMB, go to Account Management, then the third option down is Transaction Management. From there the fifth option is Download List. From there you should see everything you have ever purchased on the store and can re-download them at any time. Let me know if that doesn't work.
