Well, since I cleared IW and Star Ocean: Blue Sphere, I've been playing a lot of Rebirth. Currently just started Ch 11 and hoping I can put in some serious time this weekend to make further progress. I'm really impressed with Rebirth, sometimes the minigames get a bit too overbearing and their quality is mixed, but everything else is just awesome... best FF since 9. I think they really nailed the mix of open world and more linear, focused exploration, which really helps with the pacing. You never feel bogged down. There's a lot to see and do, the game also captures the wackiness and "soul" of earlier FFs, and the amount of music/remixes in this game is ridiculous.
I also won an auction for a cib copy of Knight Quest for Game Boy. It was a LOT of money but a good deal less than I've seen it go for over the years. I had this game as a kid and recall making it to the final area but never finishing it. I started playing it again and it's pretty basic and quite grindy (at least at the onset) but has some nice things going for it. I currently made it to what the instruction book calls chapter 3 (of 5), and it seems like a game you can finish in 5-10 hours (considerably less if you use an emu to speed up the grinding). I'm playing on a mix of Analogue Pocket and Super Game Boy.
It's a one on one RPG where you can select from 4 different attacks to use against enemies, and every enemy type has its own weakness. The overworld graphics are very simple but the in-battle graphics really shine. Animated characters/monsters, nice backgrounds. Also it's cool that there are multiple battle themes.
And as for non-RPGs, well I've been continuing with Super Mario All Stars - finished 1, 2, and 3, and up to 8-4 in Lost Levels. Finished Demon's Crest, including the hidden ending which you get a password for if you collect everything in the main game. It's an excellent almost-Metroidvania style game although some of the secrets feel a bit obscure and it definitely requires a guide to 100%... the graphics and art direction are also stellar, it's one of the best looking SNES games IMO, oozing with atmosphere and perfectly-selected palette choices. Also tried a bit of Super Adventure Island and made it reasonably far in my first shot. It's not that great of a game, it feels extremely basic in terms of gameplay and level design, like comparable to the original Adventure Island. Even the NES sequels of 2-4 (especially 4) felt more advanced than this with world maps, more exploration, dinosaur partners and more than 2 weapons. The Koshiro soundtrack kicks ass however.
