I don’t really care.
Imho, ‘exclusivity’ on pc is different from exclusivity on consoles. Console exclusivity limits where you can play it, not to mention the cost of hardware required. PC store exclusivity simply limits where you can buy it.
There are/were already a bunch of ‘first party store exclusives’ on PC, such as Blizzard and EA games. While ideally I’d like price competition between different stores to help drive prices down for me, I’m not going to get too stressed about it.
As you say, I already have a library of hundreds of games, plus sites are giving out free games regularly, so I can either wait, play something else, or buy it there.
A lot of EA games are now back on steam, and it seems like Epic exclusives only last about a year.
Given that Early Access is a thing, and it’s a thing I don’t do, I often have to wait a year or so to buy a game anyway… so if I don’t want to buy it on Epic for some reason I can just wait til it comes to Steam, probably with a discount. Functionally it’s the same as Early Access to me.
Steam being over-run with trash games is only really an issue for players if you want to spend your free time browsing the store. I almost never do that. Plus hiding adult games and anything tagged ‘anime’ has hidden a lot of the trash games.
But I’m usually following a link from an external site to a specific game, or searching for a game that I read about elsewhere, so things like trash games and store discoverability don’t really matter to me.
I get that they might to developers.
Making new accounts or downloading new launchers can be a bit of a pain, but it’s hardly worth getting stressed over, so it honestly doesn’t make much difference to me where the game is sold… I’ll usually wait for a discount anyway.
I can imagine that if/when we start getting deep into the Subscription Wars and games become exclusive to subscription services, it’ll be more of an issue. Though I guess there’ll still be nothing stopping people from signing up for one month to play an exclusive game.
