The reply is because they are commenting on a item NOT uploaded by a modder, and don't feel like they should provide their impressions. And frankly i don't really find any link with the music in this case. ****ty music for the audience and a mod in version 0.70 upload using a modder's platform with notes and bugs description, are very different stuff to be compared The workshop IS NOT a store like itunes, but a modding platform.. Define full duplex ? They can comment exactly under the mods themselves, in a very well tought comment system and you receive a notification, and you can reply. They can give ratings and there is a modder's fanbase system. Yes these are official forums and that is an OFFICIAL tool inside the sim. Who do you think that bought the sim ? Simulation enthusiasts like you and me, even people that is still wandering around these forums have now moved their license there. It seems that you think that there are only Mario Kart players on Steam, but IMO you're dead wrong. All the best simulations (even flight ones like xplane and dcs that i love too) are now on Steam.
