Splinterlands is pretty old game, I doubt it can give 100x from current price.
Splinterlands is one of the games that I'd like to play before but when I have seen that most of these games have fell down in value and it's more of a hype that's built on them, I have never checked them again.
I have played couple other games on Hive chain aside from Splinterlands, which were dcity and dcrops — both are still thriving. They don't have any hype, I would rather say that they deserve some hype.
Hive chain is itself underrated, what these evm chains are trying to achieve these days or made buzz around for things such as ENS, steem/hive accomplished it long ago.
