Hi Fireside7, I appreciate your idea and while it is certainly worth considering as a backup plan, my plan is to put my 3D modeling skills from my Bachelors degree to work developing this game. While at the same time incorporating 2D elements as well. If I were to just create a 2D game alone, I'd feel as though I were not making full use of my skills.
Of course, you should do what you think is right, but I've been through this, and what I found was that the programming, especially in setting up the framework can take a very long time. So, basically, you are only working in one skill set. I think it's best to work on all of them a little at a time. Modeling, design, and story. I also think it's best to start on a small project. With a 2d point and click framework, you can just take snap shots of models and make sprites and backgrounds, and work on game design and story, while building a 3d interactive framework. The engines, like Unity, are very basic and take a lot of work to set up, and need a lot of development time concerning scripting. It tends to end up a horrible mess at first.
