I got my Vita just over a week ago and thought I'd share my first impressions of the hardware and software. Feel free to provide feedback to my comments
The hardware itself is very impressive. I originally got myself a PSP 18 months after its initial launch and, although impressed by its near ps2 graphics, was annoyed by its bulk, weight and massive loading times (combined with the whirring noise of the flimsy UMDs).
The Vita is gorgeous! The touch screens work superbly, although the rear one should be used more in games due to its use not blocking the view of the screen. The OLED is sharp and demonstrates vibrant colours. The analogue sticks are a revelation, both in terms of having two sticks, but also in terms of being a leap year ahead of the PSP's effort.
The interface is slick and the PSstore actually feels organic and nowhere near as clunky as the effort on PSP.
Hardware wise I got a copy of Virtua Tennis with the Vita and it is superb. The graphics trump the ps3/360 version due to the brighter colours on screen, the animations are smooth and the various difficulty levels create thrilling and tight games. Definitely recommended for 20-25quid second hand. I haven't tried the online functionality yet though.
In terms of the PSstore sale recently, I got Daxter, God of War: Ghost of Sparta and Assassins Creed: Bloodlines for under £20.
I couldn't resist Daxter, seeming as it was one of the best PSP games. Glad to say it has aged well, the platforming is still superb and the Vita's big screen actually helps the visuals rather than showing its age.
God of war is still superb, no surprises here! A nice safe bet. Obviously nowhere near the ps3 releases which pushed the ps3 system so far but good fun for the train.
Assassin's Creed had mixed reviews at launch and you can see why. The mechanics of the game are pretty much the same as the original game for ps3. However, the unpredictable camera and 'automatic' climbing mechanics mean you have to play it a different way. It's a lot more stop-start than the console version though stopping to sort the camera out, but is in a word, FUN
Thought I'd share my experience with others and wondered if anyone else has some decent PSstore bargains to share. Cheers
