They do a proper job. I think, they really have the right attitude. They haven't sold nfts, tokens long before game. Partly backed by SEI grants and VCs. Tokenomics looks ok for me, their main token won't be the throwing billions out there kind + their timing is ok. Doing TGE 2 months before full launch and there is vesting, too.
They said G$MS will be listed on CEX (mentioned Mexc) and the other in-game H$RO token first will be only on DEX.
Whitepaper is not fully up to date - mostly about playing part, spells effect. Ongoing balancing going on, almost every week they fine-tune something.
Anyway, I didn't know much about SEI before this game (originally they wanted to release it on Polygon), but now i am getting know it, doesnt look bad. Fast and cheap with high potential.
They do things like this:
