Mart you find really good deals, I actually think Vita has some great games I just don't really like the handheld experience. It probably came across that I am a Smart Phone gamer which is not the case Ill play cheap games at times just in general I am a TV/Monitor gamer.
Why should I buy Killzone Vita when PS4 is going to have a Killzone game, both games have close release dates?
Well dude, I can name a 1000 reasons why one should own a PSVita, but lets go into this just one specific thing about the Killzone games and close in release.
First: I see people buy many, many shooters at the same time. COD, BF4, Killzone, you name 'em. Basically they buy the same anyways, its pew pew pew, and a story... Hardly there, but thats how I see it. What I don't get is why people buy into a yearly update on COD over and over again and just get some new thing added like a dog with an in ear speaker...
Only thing I can say about Killzone Mercenary is that it is feels more like Killzone 2 (the best of the 3 IMO) playing the beta. It is just fun to be able to play that game even when you're somewhere else aka not at home. It is a different storyline than Killzone Shadowfall too. It is months apart, KZM is next week or something, KZSF is the end of November. Why I am buying KZM is that the game feels good, visuals are really great, I use PSN on the go/multiplayer through 3G tethering on my smartphone or 3G MiFi and this shooter multiplayer is very addictive and fun. And maybe when I had my Killzone fix with this, I might even hold off buying Killzone SF till it drops in price to 20 or 30 bucks, who knows.
But hey, if you'd chose to play one Killzone, sure. Then just get another bundle out there for a PSVita, I saw one lately for USA with one year of PS+, Unit 13 and a memcard for 199 too. Just saying, that value in the bundle is very good. Even if one uses it to play KZ Shadow Fall through remote play on the toilet it is ;-)
No one can make the decision if something is worth it, but you. But for these prices, I can't understand why anyone that loves games and certainly if they love the Playstation platform (and owns a PS3 now, and will buy a PS4 soon too) to miss out on that missing mobile link and the free PSVita games on PS+. I really don't. Unless one truly hates handhelds for whatever reason smaller screen or not as comfortable as a normal controller. That last thing they made something for btw, this Nyko grip holder even incorporates an extra battery for much longer battery life, it costs around 25 USD or something.
