Tbf, there are mods that have just kept on getting more and more features and content added to them, and/or took a stupid amount of time to get to basically v1.0.

Black Mesa Source, the HL1 remake in HL2 engine… pretty sure that took a decade, was originally a mod.

Yes, by far most mods for most games are more… hah, ‘modular’, and tend to be basically just a single or few releases, but there are much more expansive mods of much larger scope, for many different games.

Basically, most ‘total conversion’ mods tend to be more like that… years of development toward a kind of end goal state, because they are basically making an entirely or massively different game, based on whatever particular original game.

That being said, I mean this just broadly for pc game mods. I don’t play Terraria much, never even heard of this mod till this post/article.
