I've been playing quite a few games recently, mostly GBA.
Castlevania: Circle of the Moon
Metroid Fusion
Sonic Advance 2 - Way better than the first game
Advance Wars
I dabble every now and then with Mario Kart Super Circuit, Konami Krazy Racers, Super Mario Land 2 and Wario Land, but I don't sit down for 2 hours and play these games like I do the others - more like a 10 minute break kind of things.
I've put my Final Fantasy IV play-through on hold for a bit. The game really isn't that great in retrospect - it's just so linear and there's a big lack of customisation for your characters. FFXIII has more character customisation than FFIV.
Over on PC, it's Overwatch for me still. I haven't played Resident Evil 7 for a while now, that will be the single-player PC game that I'll go back to. Holding out for Sonic Mania though, I will play the crap out of that game then hack it to pieces and play it again.
