Got my NES mini and lasted less than my 1 hour with SNES mini. Like there are a few games that still kinda hold up, but most of these games are waaaaaaaaaaay too dated af and not fun for more than 2-3 mins for nostalgia. Also while I'm cool with the SNES controllers in the SNES mini (though imo they don't compare to modern controllers like Saturn pad or even DS4 for 2d gaming), I haven't touched a NES controller in 20+ years and this is probably blasphemy but I think it's a pretty shitty controller. The hard angles on the corners make it uncomfortable and it's not like the d-pad or buttons are particularly great or anything.
Like the SNES mini, once loaded with roms and with a wifi controller, is probably a solid emu box for some old-school 16-bit rpgs and stuff like mario allstars and super punchout, super metroid, f-zero, yoshi's island, etc...although lacking some of the modern emulator quality of life stuff like speed up. Don't mind the $70-80 or so it cost me.
But the NES mini? Yeaaaah, I definitely feel kinda ripped off at like $70-80 after shipping. Not even sure if I wanna bother dumping roms because I don't really have any interest in playing old ass 8-bit games. Same with buying a 2nd wifi controller, dunno. This was definitely a nostalgia shelf-life box.
Anyhow, I've never been particularly into retro gaming so maybe I'm just being all weird here.
