Agreed, and in my experience (Asus board) it’s functional but a bit buggy, so not an easy recommendation. Still, if you want or need team red it’s an option. Price premium sucked, but wasn’t actually noticeably more than if I’d gone team blue. Not sure I’d do it again in hindsight though. Fully functional but only 90% reliable (which is worse than it seems, in the same way a delay of “only” a second every time you do something adds up to a big annoyance) is perhaps not worth it for my use case.
Moddb was mentioned. Another good one is thunderstore. It all depends on the game though. Valheim (and several other units based games) is very active on both Nexus and thunderstore, stalker games tend to be moddb, &c. Nexus tends to be the main one for most games though.
I mostly like Nexus (paid member), but I share the concern about it being the only game in town for most games. Nexus is heaps better as a site than both moddb and thunderstore ime, but the lack of real alternatives is putting way too many eggs in the same basket.
