I can see a hardcore gamer arrive on chain and finance his entry into various dapps, with NFT sales; each staked token a share in his future winnings in that game.

Steve-splinterlands
Steve-nextcolony
Steve-drugwars

He sets a hard limit on each, with the total worth half of his earnings in that game indefinitely. If I think he'll be great at nextcolony, okay at splinterlands and rubbish at drugwars, I can diversify accordingly. He takes what he makes selling tokens and buys his way into each game respectively.
If he wants to keep more of his winnings, he can buy back some of those tokens.

I get shares in a promising, motivated new player; he gets starting capital.
