Quoted from ForceFlow:It's not the first time manufacturers offered toppers.
Honestly, I'm not that concerned. Modders can still make stuff for older games, and alternate mods for existing games.
Just because the manufacturer puts out a couple options, doesn't necessarily mean they would be better than what's coming out of the modding community.
If it's an ip then it doesnt matter how different your art is btw. Not saying that large companies will go after you, which provides people with the above view but if you made a LOT of money as a business selling Tron art, you bet Disney would be in their right to sue you.
Heck, even though the entire internet uses stills of films and such that's still technically stealing.
