The benchmark is nominally for testing PC performance, but that's not what makes it an exciting release that people look forward to. It's a trailer and a character creator preview – and if you play solely on PS4, you miss out on all the fun.
Is there a technical reason why a version of this program cannot be released for the PS4/PS5? Obviously there's no need to test the console, but it could be relabelled as a "demo trailer" or something similar.
It would also be great to have permanent free access to a stand-alone character creator program. Currently I can't access it at all in the game because I have used up all my character slots (on the cheaper subscription with the limit of eight) so it just tells me I can't create more. And being able to play with character designs is what leads to me creating – and paying for – more alts. This would also allow new players to experiment with creating characters from races that are not available on the free trial, and maybe be tempted into paying for the full game sooner.
