i'm just thinking, I live in the uk where games are floating around £30ish and then uncharted at £35, if I buy a vita here can I make an american login and then use the US store to buy my games? it would be like £23 per normal priced game then.
yes u can, US account and buy games from US store.
but there may be some games with online play that have servers locked to US only. so you will be playing with US users only etc.
