Hey, I appreciate the kindness that SSG has shown over the whole Covid thing to my family, especially my wife and kids, who have benefited from the free access.
I'd like to suggest some ways that SSG can basically print money, and, the best thing, these ways are likely to upset very few people and won't represent power creep.
There is a ton of money laying on the table in terms of cosmetics. Not just stuff like cosmetic armor and weapons and the like, but real magical cosmetics.
What's a magical cosmetic?
Imagine one that makes you look like a human even though you're a half-elf or half-orc. The whole 9 yards, features and animations. Under the hood you still have half-elf or half orc enhancements/stats etc, but you animate and otherwise appear like you're a human (and can pick appearance within the constellation of human face/hair/etc options).
Now right now you have the wish for XXX memories, which lets you play one race and get the past life of another, but what about people who have no beef with the mechanics of a race, but just don't like the looks of it? There are lots of those. I bet they'd be willing to buy such 'skins'. There are probably even folks who'd pay for a halfling 'skin' to get 'short people IPS' (IPS works better when your character model is short.
Another option that my daughters have suggested---why not sell the ability to be a polar bear instead of a dire bear. Same stats, just a different look (they like polar bears and I bet a lot of other people do too, considering how prominent they are in pop culture).
Yet another suggestion. Make garment bags that hold like 100 garments, and make the garment bags cheap. Why? Because then people will be way more willing to buy new cosmetics. You can let your art team have fun and make lots of new cosmetics---as in at least a dozen new ones every update and a few each patch.
Let's face it, Eberron is a pervasive magic world. I bet people in that setting use magical cosmetics of this sort all the time. There are lots of people that really like certain looks and really don't like others. In a world full of illusion and transmutation magic, these are just potential customers knocking at your door.
