I love this game, but sometimes I'm left with no quests and wondering " what now?". Maybe there should be some sort of in game guidance for when you don't know where to go next? I mean it's such big world and it's a bit daunting to explore randomly!
I have the opposite problem. I have too many quests right now. Mostly because I have more time to learn skills (which give new quests) than I do to actually play in the game world, and I don't know how to find all the components for my quests.
level a little more then go to the tower in jemmitahwhatever and play in the tower a bit.
you are still at the stage of the game where the rock gives you guidance on what to do next by handing out quests every so often, typically when you level. so just focus on leveling and learning skills for now and you'll be given new things to do.
this won't work indefinitely, but it should hold your interest for an additional 10 levels or so during which time you can figure out what sort of free-form gameplay you enjoy.
