Should I buy a PS vita?

Cons: Not much "Must Have" games on the system, Frame rate on really big games like Amazing Spider-man ( Which is a direct console port ) tends to dip, mediocre camera, Not as large of a library as it's competitors Mobile and 3DS,

Pro: A decent sized library of games for both the soft and hardcore audience, Remote play, has great ports of console titles, Games usually cost $20 less then the average console title ( You could literally buy a brand new copy of Injustice:Gods Among Us Ultimate Edition for $40 dollars on the Vita, which has the same features and functions as it's $60 console brother ). and as shown by Killzone:Mercenary capable of handling good looking games.

These are my personal thoughts on the system: I absolutely love the thing. Not a day goes buy where I don't feel the need to pick it up and play it. It has cheaper and well working ports of console games, something that you don't ever really get. It also has cross play with certain games, allowing me to play multiplayer against other Vita and PS3 owners alike. Hell,on days I don't feel like using it as a game system I could just download certain apps ( Skype, Youtube, Netflix ) and dick around with those.

I will admit the Vita is not my primary source for gaming, that is still my PS3. I don't believe the Vita on it's own has the strength to keep a gamer happy, but as you mentioned you have another console do this shouldn't bother you. It's also very neat and easy to use. Nothing with the console i particularly difficult to understand, hell most 8 year olds could figure out how mostly everything works in an hour.

While it's nothing to rush towards the nearest Gamestop for, it's a very nice portable gaming system to have around, especially if you have a PS4/3. If you ever come across one for a good sale don't be afraid to pick it up.

Just make sure you buy a LARGE memory card. You'll get rid of the default 8 GB memory card in no time.

I say go for it since i was in your position last year. I bought a vita solely for P4G and it was the best investment ever! The only con i say with it are the expensive memory sticks and the lack of titles. But there a good bunch of games coming this year.

I wouldnt suggest getting one right now.
