With quests being "time sensitive," that should reflect a walkthrough that costs money. The walkthrough that can be purchased here is somewhat lacking in that regard. Granted, some quests are obvious where others are not, such as leaving in the middle of a cave/dungeon/etc. to be possible to complete a different quest.
I like the game & I'm not here to beat on anyone but I really don't like having to begin more than once or twice to finish, I'm also not one to use all the save slots up to make sure I have a descent starting point (shouldn't have to).
