Until any competing store releases a Linux client, I can’t really argue against Steam. They are a gatekeeper and almost a monopoly, but they’re also the most benevolent and pro-consumer gatekeeper that we have in the PC gaming distribution space. As long as all the competition continue to be Windows-only and, in some cases, actively work against Linux users, I don’t want Valve’s digital fiefdom to fall.
If Bungie is behind it I have zero interest without even knowing what it is. Destiny 2 was an OK game, but its god awful anticheat bans Linux users. That is a sure-fire way to make me pretend your game doesn’t exist. Client side anticheat is a plague. Do it properly on the server side.
