I personally dislike 3ED, simply because the characters sound like a horrible mish-mash: I dislike "Dwarven mage-priest-ranger-assassins" and "Moon Elf paladin-warrior-illusionists". Phrases such as "take a level of paladin" just jar horribly with me.
But anyway, that is a topic for another time. I have been working on a few quest ideas, but have found that the major problem so far is area art. As already mentioned
TOB is railroaded to the max, and most of the existing areas are pretty limited in scope, making new areas an inevitability. I have been looking at reusing and changing existing areas but I don't want them to stick out from the regular
TOB areas too much...
