First off, let me just say that if anybody wants a Vita, it shouldn't be very hard to find one on Craigslist for $150 cash money. I've bought several at that price. (I have 3 vita's at my house, one for me and two for my two boys). We bought all of our Vita's off Craigslist, and each time I got them for $150. Also, you can get most of the games for $15 via Craigslist or $20 via Ebay. I just recently got Madden 13 on Ebay for only $10.13 shipped. Normally it goes for closer to $15 to $21 shipped, but I got lucky. There are tons of great games on the Vita. I think the Hot Shots Golf is absolutely outstanding. One of the most addictive portable games I've ever played. Wipeout on Vita is damn impressive. I'm a huge Wipeout fan, and the Vita version is well worth the price of admission (especially cause you can find the game for $19.99 places).
Fifa Soccer on the Vita is another example of a top notch Vita game. Easily the best portable version of soccer in existence. When I play that game on my Vita, it's like holding a miniature sized PS3 with a copy of Fifa 12 running on it. Yeah, I know the new Fifa Soccer 13 is a ripoff, because they basically took the last version and only added a roster update. Forget Fifa 13. Just get the first one, you can probably find it for $15 or less on Craiglist or Ebay. Trust me, the game is fucking brilliant. Playability out the ying yang. There are lots of fun demos to play on PSN as well. Super Stardust is awesome. Montezuma, the match 3 game is fun to play once per day. It's one of those freemium games.
GameStop had Mortal Kombat vita for $10. I'm not sure what the price is now, but so many of them were sold at that price, that it shouldn't be hard to get from somebody else for $10 to $15. It's well worth that. It's a damn good game. Lots of good games to get on the cheap.
