I don’t know about that. While they certainly do inspect the ideas for balance and obviously to test if they work, I’d say some of the CBMs I made were “half-baked,” in all honesty (I didn’t expect Railgun to go in, that was half joke, half test). I don’t think their standards are as stringent as people would expect. This probably has something to do with encouraging contributions (if my first CBM mod had been rejected, I wouldn’t have bothered to submit any further).
I’d feel a lot more comfortable if the game had a modular mod framework (I’m sure that’s in the works since it’s been suggested before to have separate mod folders, but right now everything goes straight into mainline). Right now, I get this nagging impression that people are trying to “claim territory” by getting their mods (and names, if they follow this trend) integrated into mainline. I’d hate to see this game devolve into Twitter Days Ahead (I don’t actually use Twitter, so I have no idea if that’s an accurate analogy, but I hope you get the idea).
