We're talking about EOL plans here. You don't have to care about DDOS.
> This is only feasible if the multiplayer backend is a simple server binary, which in many cases it's not anymore, but a full cloud architecture you would find for any SaaS app. There additionally is the issue of licensed libraries, which may prohibit redistribution of the server binaries (and may e.g. be bound to a per-host pricing).
I have multiple issues with this framing:
1. We're talking about regulation about _future games_ that haven't been made yet. SKG doesn't want to regulate existing games. So we're not talking about retrofitting an EOL plan on games that already rely on complex backend. If you're planning for it from the get-go, getting an architecture that isn't so cloud-reliant isn't that complicated.
2. Even if we accept the premise that a game _absolutely needed_ a cloud only architecture to function for one reason or another, that doesn't prevent releasing the architecture binaries.
3. Licensed libraries may have redistribution prohibitions _today_, but should EOL regulations come in place, you'd find that those libraries would quickly move to allow redistribution for EOL purposes, as otherwise studios would just _not use them_.
> Take your pick from[0] or a competitors website: PEAK, Content Warning, Gorilla Tag; All games from indie developers that heavily rely on good networking that wouldn't be feasible to be replaced.
AFAICT, Photon Fusion is fully compliant with SKG already - it supports games where one player is the "host" and all comms are P2P. Players can direct connect to one another. While it does work better with a STUN server or with Photon's cloud, they are not *necessary* for the game to function.
Photon's Voice offering might be different, but turning that off for an EOL plan is totally acceptable according to the SKG's wanted regulation - they would fall within the same category of "extra services" that aren't part of the core game.
And _furthermore_, of the three games you cited, I know for sure that PEAK and CW are playable fully offline. They're already SKG-compliant even if photon fusion was somehow not. I haven't played Gorilla Tag or looked into it, but I think I've already made my point clear.
> Ah, yes the simple option of "completely tank your playerbase".
WoW still has active players in the millions. FF14 has a 25k peak concurrent players in the past 24h. There are other success stories. But sure, it "tanks your playerbase".
