I do currently and I'm not only holding tokens from them I'm also playing the game as I find it enjoyable. Those that are mentioned in the OP are kinda older games with a lot of token already minted, though it's still good if they developed a burning mechanism to balance everything.
I am actually playing Night Crows, a similar game with MIR4 but it has way better graphics. The game is not new actually, but the integration of their token in crypto world is what makes everything interesting.
This game may not let you earn crazy returns like what happened with Axie, but this game is for sure has more stable condition in terms of it's sustainability.
