As much as I'd love Destiny on my Vita, the fact it'd be always online means I'd only ever play it at home, since the other places that I usually take my Vita don't have wifi, so it'd render the game kinda pointless, I'd just play it on my PS4 instead (plus my Vita wifi is a bit spotty, I'd hate to drop from the end of a raid accidentally and not get any rewards!)
One game I'm really pleased I picked up though is Pinball Arcade. I grabbed the first season pass and while it seemed fairly pricey I did enjoy the base tables included with the game so I took a gamble with it. And I'm glad I took the chance, I've barely played anything else on my Vita all month, its such a brilliant time waster - 10 minutes to spare? Hit up a pinball table and aim for the high score or go for one of the challenges. A couple of the tables are a bit underwhelming (Big Shot feels borderline unfair at times, feels like it screws me over) while other tables are just brilliant to play (the Star Trek table is really impressive with all the secrets it packs into the holodeck alone!)
Also, I've been playing through my import copy of Time Travelers. Its such a shame that this was never translated (it did badly in Japan from what I understand) as its a great interactive story (more in line with Telltales releases than a visual novel, since its fully animated). The story and characters are brilliant, I'm now on the final chapter and I'm hoping for a happy ending (the previous chapter being fairly bittersweet).
