Help,i suffer underation
I'd e.g. offer testplaying/streaming on youtube (when browsing here in the community/forum's "game-feedback" section), if player's would be open for suggestions or getting their released versions tested by other dev's.
discord do have a disboard-page which refers to severs and there are also tags like "gaming", "twitch", etc. about 3 platforms you've mentioned, I didn't heard of them yet. Still maybe even collaborating with users could be fun e.g. offering translations for their game/s, if you could get suggestions/feedback to yours?
Does it depend if you would own a high amount of followers or just less while they adore your work and supporting you? :-)
Personally I guess many views for videos sounds cool for statistics, but if fans liking you as person it somehow sounds quite more personal in a positive way? They'd maybe offer to assist them just expecting something great just because of subscribing you as dev/user there?
