I was kinda thinking that different games that accepted a Let's say NIP-7000 character would be able to nerf some attributes and buff others as they saw fit to limit supra-powerful characters. Some might allow some inventory items a character might bring (each with it's own attributes) but not others or none at all.
Existing games I figure won't even want to devote time to figuring that all out but new games will always be made. If the NIP exists when they do then it would be easy to say "This game is NIP-7000 compliant" .
I mean, the whole idea is a stretch but at least I wouldn't have 15 different Palladins.
