I wouldn't mind something like this. I have certain games listed with the tag "Advanced" but I list the Advanced games at the bottom of the list, for obvious reasons. The thing is, with how SBVR lists the games in their sections, it shows the game in the first Tag section and then it wont show up in any of the lower Tag sections that it's also been tagged in. So for something like Onward or Zero Caliber, I have them as Advanced games but also as Shooter, I list the Shooters as my second category, so both of those games will show up there with things like Space Pirate Trainer and Shooty Fruity and then they wont even be listed in the Advanced games at the bottom of the list.

Having some additional difficulty tag that when people click on a title, it actually prompts them "This game is considered an 'Advanced' game and is far more difficult than others we offer. If you're not very familiar with VR, then we suggest that you try out some other titles before you play this one."
