Three PSP titles appear on the PSN bestsellers list for October. It makes sense, considering the launch of the all-digital PSP Go. Surprisingly, the much-anticipated Gran Turismo PSP didn't top the charts. Instead, PSone classic Final Fantasy VII took the lead once again, undoubtedly boosted by nostalgic RPG players wanting to relive Cloud Strife's cross-dressing adventure on the Go. Here's the full list:1. Final Fantasy VII (PS3/PSP)2. Zombie Apocalypse (PS3)3. TMNT: Turtles in Time Re-Shelled (PS3)4. .deTuned (PS3)5. UNO (PS3)6. Gran Turismo (PSP)7. Marvel Vs. Capcom 2 (PS3)8. Ratchet & Clank Future: Quest For Booty (PS3)9. Critter Crunch (PS3)10. God of War: Chains of Olympus (PSP)Konami's Zombie Apocalypse stood as the top new entry, while interactive art experience .deTuned managed to snag a few purchases from Trophy hunters looking for some of the easiest achievements ever created. Critter Crunch's low sales numbers managed to snag it a 9th position -- which either means sales picked up after the free demo, or October was not a very good month for PSN sales at all.
