can’t think of any technical problems, it just seems to be being able to make it easier for people to play new gamemodes
stuff that comes to mind would be having a specific gamemode browser, listing all the current gamemodes and total servers playing them, allowing you to click in and list all the servers for that gamemode.
some easy way to ensure the client is sent all the specific gamemode data would be pretty awesome too… something along the lines of zipping up the whole content folder and downloading it automatically (without having to mess about with both making sure every file is available to fastdownload, having it go straight into the garrysmod/ folder cluttering up that stuff) would ideally make it easier for gamemode creators making being able to ensure the client gets all the content, server owners as they’d have to set up less and clients as they would ideally have all the content separated, could even go as far as having it list the gamemode specific content in the same way you just implemented for addons in the spawn menu

the whole starting a new game in a different gamemode then only listing servers for that gamemode sounds like it would be awkward for users but can’t really say without seeing it in action I guess
