I like the idea that Splinterlands is looking for other playable format other than card battler. Not sure if devs read this but like what I've said before, one main reason why League of Legends is still relative up to the day for more than 10 years in the game is that even if they grow their main game, they still add new playable features like Team Fight Tactics, or venturing to other game format like Runeterra. This is a really good move for Splinterlands and if this tower defense game pops off, I wish they also focus on this while growing the card game.
We may just see the next Riot Games of cryptocurrency.
