Well, it's lighter and has a longer battery life, plus internal memory, but inferior screen quality, which I think was the biggest gripe people had with it. I just don't have the cash for it. xD;
Aww, what sort of games were you looking for? Vita has a lot of good quality JRPGs, but...not much else, aha. That won't change anytime soon either, as there are no AAA titles planned. Although I won't be losing sleep over this, aha~
That was the latest one, right? Wikipedia tells me Story of Seasons is due out in 2015 in the US (with the standard "TBA" for European territories, as usual. xD) so I'm guessing you'll get that when it comes out? :3
I still need to play Rune Factory 4...xD
