I don't get your argument. You say that 90% of the game is bloat but so what if you can ignore it.Some people like to talk about how bloated TW3 is, but they fail to mention that 90% of the bloat is optional. No one is forcing you to do any of those sidequests or explore all the POI, and it's certainly not necessary in order to finish the game.
I don't know man... How about... Maybe... Having a game that has a tighter world with less bloat but more meaningful content?
I said that 90% of the bloat is optional not that 90% of the game is bloat.
TW3 already has a significant amount of meaningful content. You can just ignore the filler if you don't think it's worth it. The main quest doesn't need to be any larger though.
Content that you can ignore is content not worth playing.
Whether or not something is worth playing is entirely subjective. Many people like that the extra content is there.
