The OG Wii
Reasons -
- Cheap! ($20-$100)
- Fun, physical ways to interact with games (eg: Wii sports, Wiifit) that make casual gaming accessible
- Despite being ancient, homebrew still a thing. See - Minecraft and Beatsabre ports, MK etc
- Easy to mod
- Cross play with select NDS titles (before it was cool)
- Decent sized game library; gems and slop to be fair, but you won't be bored.
- Pretty good emulation for such old system (16 and 8bit)
- VirtualWare games
- Some really novel titles
- No region lock
- Built like a tank. You can completely bypass failing disc drive with SD or USB.
- USBLoader GX (free) + Autoutlet HDMI out ($20) = you won't believe how good 480p can look when tuned (eg: Xenoblade, SMS, SMG etc)
- Apart from the red one, they're all basically GameCube compatible (either directly or via Nintendont) at hardware level. That's an amazing library of games on its own.
- Instant on; no DRM shit
- Tiny, quiet, cute.
And all that for $20.
