I'm currently juggling Day of the Tentacle Remastered, World of Final Fantasy, Darkest Dungeon and Resogun on the PS Vita. Sounds like a lot, but I have a system.
I never played Day of the Tentacle before, but decided to check it out since it was free on PS+. I never bought it even though I was mildly interested, because I was worried it would be less like Monkey Island (which I love) and more like Grim Fandango (which I'm not such a big fan of). Turns out it was more like the former, though, and I'm having a blast - I was laughing out loud more than once in my first session with the game, and I love the design a lot - the only downside is that now I want Curse of Monkey Island on the Vita yesterday. Seems like an easy Platinum, but I'm staying away from guides as I want to get the full experience and solve the puzzles myself.
World of Final Fantasy was a semi-impulse buy on the PS Store sale, and in recent years there have been few game types that have appealed to me less than JRPGs - yet, I seem to have had a tiny itch for something like that, and this game is certainly doing a fine job scratching that. It feels more like a Final Fantasy to me than the last few Final Fantasy games that I've played (it's worth noting that I loved - and still love - the old games, up until IX), and I'm having a ton of fun with this unlikely personal hit. I'm gunning for the Platinum, but it'll certainly take quite a while.
Darkest Dungeon is an "old" love/hate-counterpart of mine, as I played it on PC a year ago when it came out. Upon hearing it was coming to the Vita, however, I stopped and waited for the port that would make it a REAL GAME. I'm constantly stumped by how weird the controls are on the handheld, but with a game this good, it's easy to overlook something like that. I have a crazy fever-dream of getting the Platinum Trophy, but I'm not too confident at this moment - maybe one day.
Finally, Resogun is no new acquaintance to me - I intended to Platinum it a long time ago already, but due to my surprisingly wholesome suckage at it, I dropped out. I picked it up again just recently, and started from the bottom, re-learning the game on Rookie difficulty and trying to study all the tricks that would make me better. I feel I've improved considerably already, and I'm pretty confident that I'll get the Platinum pretty soon - I'm at around 70% at the moment.
