That's the reason why - didn't really buy any games for the past couple years while I was finishing up CSH since I didn't have the time or the money for them. Now that the game is out (albeit I'm still working on updates & ports), I have more free time & some money here and there. So far on the Vita side since we released our game, I've picked up Trails SC (technically a PSP game) & Tales of Hearts R (since it's only about $10 in the sale now and I'd like to try a portable Tales game), but that's pretty much it.
Ok I pretty much did this myself - catch up on Vita games over the last few years.
My recommendations are:
Dragon Quest Builders - I'm playing the PS4 version right now, but I think the Vita version is pretty much identical gameplay wise and from what i've seen looks really good on the Vita too. The game is so relaxing most of the time, when there are battles it does get a little more full on, but most of the battles aren't very difficult. The beauty of the game is that there's always something to do, something to craft and build. Going out into the world and finding resources is also bizarrely fun.
Dragon's Crown - It's like Diablo but as a 2D side scroller. The art is worth playing alone, but I think its one of if not the best Vanillaware game. Vita performance is excellent.
Dungeon Travelers 2 - This is a really impressive dungeon crawler, where the gameplay systems are intuitive and fun and the concepts aren't too hard to grasp, yet the job system really makes this game incredibly deep. There are just countless ways to upgrade your characters and adjust your party. The only issue is if you screw up your levelling up you might find you end up having to grind a bit to skill up in other areas. Otherwise the game is superb and the dungeon crawling is really fun and throws different things at you every chapter. Excuse the unnecessary sexual content.
Everybody's Golf / Hot Shots Golf - This is an oldie, but if you haven't picked it up, its still available at many places for cheap. Such a great golf game.
Oreshika - I haven't played this yet, even though its been sitting on my system for almost 2 years. But the game is so beautiful, its definitely a must buy just to check out the amazing art. Only on Vita too, if I'm not mistaken. There's a physical Asian region version with English.
Shantae Half Genie Hero - I hear this one is getting sold out at most places, and the game looks gorgeous on the Vita. Worth picking up soon.
Steins;Gate - My favourite Visual Novel. Just a huge rollercoaster ride from start to finish, doubly so if you like time machine stories and science fiction. There's a sequel Steins;Gate 0 if you like Steins;Gate too.
Superbeat Xonic - Music game genre might be past its heyday, but Superbeat Xonic is a great game with music that feels really fresh. From the devs that made DJ Max Technica Tune.
Terraria - The best way to play Terraria is on the Vita and just
$14 on Amazon.
Utawarerumono: Mask of Deception / Mast of Truth - Two part VN/Strategy game with Mask of Deception having released in May, and Mask of Truth will come out in September. Have to watch the anime first before playing the game. People are already raving about the game.
Ys Memories of Celceta - Most of the other Ys games are on Steam, but not Memories of Celceta (which I believe is also not on PS4 or any of the other recent consoles for that matter).
Apologies if the screens used aren't from the PS Vita version!
