imo, even cosmetic micro-transaction stuff is disgusting. In single player its absolutely intolerable and in multiplayer its at the edge. Not only it makes creating almost non-existent content more profitable, likely at the expense of worthwhile content because any development costs money. Why make the game better when you can create more cosmetics. I'm not saying creating cosmetics is trivial, but making new skin vs creating actually new content are on completely different scales, especially when those new skins are sometimes just recolouring old ones.

Not having access to cosmetic stuff without paying extra also often detracts from the game for me. As example, in game v-rising there are some cosmetics packs for different skins for your castle's furniture. While you can furnish the place decently with stuff you get, you can be much more creative if you have access to the alternative skins.

If they were all part of some larger expansion pack with something more than just skins, I could accept it but if i have to buy every theme pack separately, I'm not going to do that. I would have much less money available if i had to buy every damn dlc to every game I play. I'd say building and decorating your castle is 50% of the game, less if you don't care about how your castle looks at all. Not buying these dlc make the game less enjoyable for me.
