The fees are pretty low, but do spike at times. Many games are handling it quite well and players know when not to play too much when fees are spiking. So far in testing it went quite well. Depending on how active you are, you might not need to do any tx a day since most of our ingame mechanics are simple wallet signings that doesn't cost any fee. Mostly the fee only comes in when changing the NFT (upgrading/burning/selling). So even with this starter pack, once you pay the gas fee to mint the pack, you can play without any extra gas fee.
