i play on ps5 as my main way and only way of play tsw games and i would love to know if it is possible to install pc editor add ons onto ps5 or not
Depends on whether or not, Dovetail want to support the dedicated add on. If not, then it's only available to PC users (and even that is vaguely because there still is no official cooking feature built into the Editor, just a fix which may not work in all cases). If yes, you can have it on consoles as well. However, this case is very unlikely. DTG seems to not get in touch with creators from their part, and so far only 1 project has been confirmed to get released through their third party programme.
