I would happily support an Obsidian development. I wouldn't like to dictate a sequel or even a particular genre; I just want something superbly written with amazing dialogue and characters. Planescape: Torment is probably my favourite game ever, but for me what makes it so good isn't the isometric viewpoint, AD&D mechanics or even the Planescape license - it's the writing. I'd pay up front in order to provide Obsidian free rein to explore their creativity in whatever form they see best. Just make something amazing.
