Because a big “Join our community discord server!” on the game’s title screen isn’t enough apparently. They have to put a flashy animated GIF at the top of every update notification, change the name of the game’s Steam forum to “Join Our Discord!”, and even reply to posts in the Steam forum saying “You should join our discord so we can chat about it!” as if a forum isn’t a good place to chat about the thing that’s already being discussed.
Bitch please, if I wanted to be in the hell that is Discord I’d already be there, you can stop asking.
A lot of small indie or fan games love to hide on Discord. Got banned? Appeal it on Discord. Wanna submit feedback? Come on over to Discord!
What do they gain from this? Besides making their content impossible to find in search engines, clearly they’re optimizing for maximum inconvenience and peak exclusivity. Nothing says “accessible community” like forcing players to re-ask the same questions in a walled-off chat nobody can Google.
