But why Sandbox and not, for example, Decentraland? ;-)
As for me:
Dose - whole new application of play-to-earn, with only a handful of projects to compete with
Crabada - sounds corny, but I reckon it has a chance of becoming the Avalanche equivalent of Axie Infinity
Realm - low market cap metaverse that also looks really neat
Mist - same here
Fear - not much of a fan of horror games. But the market is there, and so far there is only one crypto project monopolizing this genre.
