I think fans of JP games have a right to be at least a little paranoid about EGS. It may not host any JP games at the moment but it's really a matter of "when" rather than "if." It's a big market after all and if it's true Epic is looking to damage Valve/Steam, then JP games represent a big chance for that. Just look how many days Octopath Traveler was a top-seller! (or NieR Automata, MonHon World, etc...) Personally I would be steaming (that's a pun!) if like the next big Final Fantasy got scooped up, or Code Vein, Babylon Falls, etc... Like I'm sure FROM fans would be pissed if Elden Ring got snatched huh?
There is nothing in this world that will make me install EGS or make an account for them... but that doesn't really make the pain any less if something I was looking forward to got taken from me for an extra year or permanently even. Telling people to shush up or quit being paranoid... it's not really helpful.

derExperte said, many people thought Devolver wouldn't take EGS money but they did. The chronicles of EGS has more letdowns than hope, people keep hoping this dev or that pub won't take the money... but so far? Nearly every Dev/Pub approached has taken the money. We have a 100:1 stories in EGS favor Vs. against them.
But well.... opinions and all that I guess.
