That is quite the collection! Fuck!
Do you have any digital copies on your Vita at all (PS1/PSP aside)?
I think I have only three digital games: Escape Plan, Sine Mora (PS+) and the Motorstorm game. If a game is only released digitally in the US and physical in Europe, I track down an european copy. I want to have all US released games and all UK exclusives. I can try to go for all EU exclusives but I still haven't made a list of all games released in Europe. Yesterday I discovered a game that was only released in Spain, now I want it in my collection.
You're making me want to expand my collection.
You should do it. Retail Vita games are amazing, they look very nice and it's very fun to track them down. The Vita still doesn't have a lot of games so the set is a bit easy to achieve right now but some games already are getting more hard to find.
