I've been a bit all over the place, something of a gaming drought, then started playing several things at once. Now I'm playing:
Lost in Blue 3 (DS) - it's not exactly 'fun', but I'm looking forward to exploring the tropical island and seeing what stuff I can make for the survivors.
Shantae and the Pirate's Curse (PS4) - Wonderboyesque heaven, absolutely brilliant stuff.
Stoneloops! of Jurassica (PC) - this one's a marble-popper, with a little paddle at the bottom of the screen, so it plays like a combination of Arkanoid and Zuma, it's got lovely presentation and sound FX. Didn't know of its existence till I found a copy in the charity shop. I love casual games from the 2000s (this one is 2009), such an interesting range of topics, genres and graphics.
Vampire Hunter D (PS1) - this could almost be Resident Evil, if you ignore the player character, it even has tank controls (which makes combat a pig!), it's interesting though, a new action adventure game set in a castle to explore! I played this yeeeeeeeeeeeeeears ago when I was a kid, but couldn't get far and could only remember that there were some femme fatale type enemies (turns out they're dangerous swordswomen with elasticated claw-hands wearing flowing dresses, so didn't remember wrongly). It's tough and I stupidly used all my health restoratives at the beginning of the game ('using' items from the inventory screen hot-buttons them to the square button as well, so when trying to use D's hand I was using a health potion instead), but it's certainly an interesting adventure. Hope I don't get squashed by a boss.
Hybrid (PS1) - budget FPS, turns out pretty playable actually! The character artwork has a very amateur manga-fan look to it, which reminds me of manga fanzines etc. from my youth, certainly want to play through it. The PS1 was a system I used a lot, but there's squillions of games I never played, it's fun trying new ones out.
