Various ones at the moment:
Mr. Driller Land for the Switch. Bought it last summer on a whim since I recall it being kind of a holy grail of the series that was never released outside Japan. It's a great pick up and play game, hence why I've been dabbling with it again. The various Namco cameos sprinkled throughout make me smile.
No More Heroes for the Switch. I bought this and the 2nd one when they were released for it late last fall. I loved the original on the Wii (Possibly my most played Wii game after Dragon Quest Swords) and want to refresh myself on Travis's antics again before I try the 3rd one eventually. With my Wii being essentially dead, I'm grateful to have these on a modern system. I've also got NMH Lost Paradise for the PS3, but again, I wanted for modern systems. Still probably the best overall game Suda has ever made that isn't Shadows of the Damned.
Shin Megami Tensei for the SNES. Playing it via a translation patch and it doesn't mess around. I honestly haven't touched it in a month or more because I went through the SNES remakes of Megami Tensei I and II and frankly, I'm so sick of looking at maps lol. It's clunky as hell, and accessing a map takes about 3 steps too much. Obtuse as hell. I'll get back to it though, as there is potential and good to be still found within.
Of course, come September 24th, I will be playing Judgment 2 for the PS5. I love the Yakuza games and really enjoyed the original Judgment spinoff. This one looks to be worth it for the amount of classic Sega Master Systems contained within alone... And considering the original had the best end game half out of any Yakuza game yet, IMO, I have some super high expectations for this one. Also hyped for 60FPS again in these games.
Oh, and I busted out that Namco NES collection on PS5 earlier tonight to play the 8 bit PacMan CE that's on there. Pretty kickass game and well worth buying just for that if you enjoy PacMan at all.
Tempted to play Crystalis on the SNK 40th anniversary collection sometime soon. One of the best adventure RPG games for the original NES that isn't Zelda.
