I'm planning to mostly rely on digital downloads via PS+. Hmm better get 16GB onwards eh. Basically any Vita (US/UK/SG etc etc) can play any games regardless of whether it's R1 R2 or R3 right? Can I have both EU & US accounts free games from PS+ Instant Game Collection on each account available at once?
Suggest you get 32 GB then. Might as well go all the way. I'm using one and its full of PS+ games already.Technically you can play any games that you bought physically (on the gamecard) irrespective of region.
However for downloads you will need to create and stick to 1 account (US, EU or MY, etc) and all your purchases are restricted to that region. You can always reset (see first posts or the technical section for details) which can be troublesome as you will need to redownload everything again. Some buy 2 memory cards separately so all they need is reset the vita and plug in different game card.
If your next question is gonna be about the best region to stick to, then read the few posts prior to this as this topic crops up all the time.
