You're right. Gala on ETH felt like a concern to me and the gas fees to transact definitely is felt. For now, I call it the price to get in and that it'll come back around in the end. I believe that some of the Gala games aren't being release until their side chain is launched.
Some of the Gala Games, Illuvium, and Star Atlas are upcoming blockchain gaming/NFT plays I've been researching. There are many more, but I'm trying to pick a few to focus on. Splinterlands is interesting to me, but I don't seem to have that much fun with the style of game play. I'll still stay involved and grow my accounts slowly, but I'd hope that the dynamics will become more intricate over time.
