I was tempted because the Donkey Kong game looked fun, but then I remembered I've only used my current Switch to play Gameboy/SNES games I could easily emulate so I bought a Steamdeck instead.
Be careful with that if you're talking about 360/OG Xbox titles. I bought a Series X thinking it was fully backwards compatible with the full Xbox library, but it's a relatively tiny selection of games and a lot of the best ones (like Tenchu Z which was never ported anywhere else) aren't included.
Honestly depending on your situation you might be better buying what you can on PC or getting one of the old consoles second-hand. I've been collecting Xbox games for a while and they are almost always much, much cheaper than PS2/Gamecube games because there's so little demand for them.
