Most disappointing is how perfunctory the main quest line feels, boiling down to another simplistic binary choice - what I like to call the Platoon Dilemma - between two surrogate leader figures one a bloodthirsty killer, the other a hand-wringing pacifist. There are a couple of side quests, but nothing particularly robust.
It's mostly a selection of slim fetch quests, none of which are optional. There's a fascinating tale to be told about this place, so it's a shame that Honest Hearts doesn't really offer much to sink your teeth into where quests are concerned.
