I'd instabuy a Windows 3.x mini, or, even better a Win98SE Mini. Got a couple 16 bit games that don't work with a modern 64 bit OS, plus tons of Dos and other Windows games and programs of that era.

DOSbox?

Do they honestly and absolutely need one?.

All these mini boxes are, are a tiny box with a tiny selection of games, a short power and gamepad cord, while costing something silly for it's age.

XB doesn't have the heritage yet. Plus, look at how bad the PS mini did. Maybe in another decade XB will be ready.

They need an XBOX Slim first, then an xbox MINI.

Most of the mini consoles are pre 2000. With the exception of PS1 (doable storage wise), the amount of storage you would need for the games on this Xbox mini console would make it too expensive. Or the storage would be small and you would have like a handful games on it. It wouldn't make it worth it then. The controllers would also cost way more than your NES or SNES controller for your NES Classic or SNES Classic. It just doesn't make sense financially.

Would buy. It would need an SLC NAND drive though for longevity/reliability reasons.

Halo, Fable, Forza, Panzer Dragoon, Jetset Radio, Jade Empire, Phantom Dust, Crimson Skies, Conker were all great.

Sprinkle some titles like Morrowind, Oddworld: Strangers Wrath, Otogi, Amped, Shenmue, FarCry, Doom, Deus Ex, Dead or Alive as fillers... And you have a very solid Xbox Original Mini with a great lineup.

The Playstation Mini was just shit in every regard. - Terrible choice of games, poor emulation quality and lacked features, it actually deserved to fail... It's only thanks to modders that the mini console was worth saving from landfill... The Playstation Mini isn't going to be representative of all mini consoles going forward.

Its pointless, because the X1 plays OG and 360 games. Basically defeats the point.

Every Nintendo Machine since the Wii plays NES games (GC included if you count Animal Cross) The NES Mini still sold 3.6million units, those mini consoles aren't about just the practical use of them, they're also collectors items as most of them (heck even the PSmini) are lovely little ornaments of the original machines which have the icing on the cake of being able to play some of the key titles from those systems, they're amazing as gift ideas for older gamers and like I said, they're nice collectors items as well as being a playable system.

Also I think there's another reason the OG Xbox couldn't work as a Mini...

Xbox is HUEG!

That only works with the Dos games. Any Windows-only game from that era doesn't work with it.
