The steam deck just barely emulates the switch, so I think switch 2 emulation is out of the question unless there is serious performance hacks. Ryujinx likely would have been able to emulate the switch 2 one or two years after launch just like what happened with dolphin and the Wii. but Nintendo illegally got them shut down
I used to play Roblox a lot, and there definitely is some fun to be had on that platform but its not really a proper game developing software. your “game” is completely reliant on roblox’s servers and site, and they have control over anything you do on roblox. Roblox is a lot simpler than developing a “real” game, so I think it’s closer to garry’s mod than unity or Godot.
Stalker Anomaly is available to download for free on moddb.com, and its actually a modded version of the original games. but GSC has allowed them to redistribute the game for free.
