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.
That's usually a sign that the person can't overcome their own OCD tendencies and blames the game for being too big.
It's not about that, it's more about the fact that the resources that went into creating those quests and zones could have gone elsewhere.
Yeah, it kind of sucks that we didn't get multiplayer and microtransactions.
