Pretty sure he's talking about the new one, since the title say's, "which should I buy, sly cooper or little big planet for ps vita?"
Personally, I like Sly Cooper's gameplay better. If however you've enjoyed both in the past then buy whichever is cheaper. Pretty sure you can probably find LBPV cheaper.
Probably true, but just playing devil's advocate - OP could have meant "sly cooper" (PS3 or Vita) and "little big planet for PSVita" . Just an example here of how the PS General forums aren't as organized as the old subforums; I don't think Brit usually participated in the Vita forums.
Which is why I said "Pretty sure".
However, seeing that the OP took the time to put "PS Vita" in the title at all and didn't add PS3 or a 2 or 3 after Sly Cooper, I'm going to stick with what I said. lol.
yes I meant ps vita games exclusively.. mystery solved! I will be buying both but from the looks of it little big planet will be my first purchase, then sly cooper then, SOUL SACRIFICE!!
