After much soul searching, I suppose my results are pretty clear; Moving to 3d wouldn't do much for the project as it is right now. There also isn't an easy way I could make 100RTBD's style change drastically, unless I found someone to do custom sprites for everything, more or less. I also thought long about if I should change certain things, gameplay-wise. But no, if I want to finish 100RTBD, I have to stay on target.
I could probably spend 100 hours right now trying different things; How would the game play if you removed the RPG elements? Got rid of the items and equipment? This is usually good practice, since you need to do this - think over what you've already decided - in order to make better games, but I want 100RTBD to be finished. I want to tell my whole story, add the whole of my items, weapons and skills, I want to make the game that I had designed in these first few forty hours or so.
I don't want to abandon such a project and going back to the drawing board would surely - through questions like 'if I am to change it that much, why not scrap it and start over with some new cool ideas?' - signify impending doom, if not for the idea itself, maybe for my motivation, and I don't want to risk that.
Time spent on the project so far: 633 hours
Currently working on: Continuing the story
