I know that somewhere in the Roblox ToS it says that you cannot sell games or groups, but Im wondering if selling the game as an asset or group of assets is allowed.
Are we also allowed to sell individual assets within the game?
At what point would that become against the Roblox ToS?
If it’s between two consenting users, the sale of games is allowed. See here. However, there are no built-in regulations for this kind of activity, so be wary of scams.
As for selling individual assets, I’m not sure what you mean. If you’re talking about gear or clothing that you created, then yes you can. Just search up “homestore” on ROBLOX and you’ll see plenty of examples. As for models and meshes, I don’t think you can sell them through ROBLOX (in the library, all assets are either free or not-for-sale). You’d have to sell those assets on your own, outside of a game.
Regardless of what you are selling, as long as it is your own intellectual property, you should be fine.
No? Read the post you linked:
Do not give other players Robux or items in exchange for a game, because there’s no official system which allows them complete the trade.
… and the rules:
- As discussed in Roblox Terms of Use, you cannot (and you cannot allow others) sell, trade or give away Robux, digital goods or game codes except through official channels on Roblox platform. For example, you cannot conduct such transactions through chat, Roblox Groups, or third-party apps or websites. You also cannot buy or sell Roblox games or Groups.
OP is asking about selling the game’s scripts and builds separately, rather than the whole game at once, to avoid this issue. It should be fine, since #collaboration used to have an asset marketplace for sales similar to this, just be careful who you give it to.
In my defense, the post I linked allows for selling outside of ROBLOX between third parties. But I did not see the second article that you linked that further clarifies the issue. Thanks for pointing that out! Please note that I also addressed the issue of selling individual assets as well. 
Yeah, I was just clarifying that he was likely referring to models and not clothing.
You “can” do it, but you kind of have to “disguise” it if you want to buy an entire game. Like in GRP (Group Recruiting Plaza) Discord, people disguise the buying of games as a “fully scripted simulator map” or a “fully scripted cafe” and it is allowed in that Discord. People also sell assets on there, there’s people literally every 10 minutes posting a message that says stuff like “Handcuff system for sale” or “Cafe system for sale”, or stuff like that. Selling assets directly on Roblox is quite difficult, and since it’s either free or private when it comes to models and scripts. For games, it’s almost impossible to sell on Roblox anyway. I would suggest you join a big Discord that does allow the “selling” of games and assets, like GRP (they allow asking for investors on there too, so it’s quite convenient).
What I mean is, I sell you the scripts and builds as separate assets for one price.
Basically just selling the game as roblox model files.
Is this allowed, and would it be allowed just to sell the place file?
