Okay so this looks like they repurposed the original Blue Protocol into an proper MMO with Genshin/Wuwa combat but no gacha (seemingly), FFXIV boss encounter design and an actual character creator. Interesting.
I could see the potential as there are no direct competitors right now except maybe PSO2NGS but that one is on its death bed, so.

It's all going to come down to how bad they try to screw people with P2W slop and if the content has lasting legs and tries to actually be deeper than a puddle because that's usually what kills that sort of game on the long term. I really hope the combat is engaging enough and not the usual mobile 1 button crap.
