I think it was the right choice for ROBLOX to end support for XP and Vista, The average ROBLOX player (which are mostly kids and early teens) plays the game on Mobile, or Windows 7, 8.1 or 10, or rarely XBOX ONE
There doesn't seem to be any other way to play ROBLOX, Finobe, a old revival with a community that reminds me a lot of a forum's "random" category, doesn't seem to be compatible with XP and Raymonf doesn't want to...
At least Minecraft should work with the old launcher.
Yeah, but they will not be able to play the games, Unless if it's a revival.
