@Acharis: I said I never wanted to pass off an idea and just have someone make my game for me.
The prospect of working on bringing my ideas to life has always been exciting. Using your gardening analogy what I had done would be closer to studying Botany, having an understanding of every plant as well as how each could realistically grow, generally knowing what would be required, then realizing I'd be setting to plant the botanical gardens.
@Legendre: I understand what is being said in regards to spending less time thinking and more time doing.
To a certain extent a large part of the doing is thinking and planning in my opinion. I wouldn't build scale models of increasing size if I were planning on building the empire state building. The models in between would be a waste when I could have been developing floor plans and different architectural facets.

If you can prove a theory without physical experimentation why spend the time on experiments that could be used towards building your proposal? We all have our ways of developing in which we flourish and expand. Some are more physical and gain insight through construction. Others are more cerebral and approach things through foresight and planning. Like it was said, you could day dream all you want but if the resource/time constraints aren't feasible, it is unrealistic to start a project. Yes, I could have started small, building light version of things which weren't exactly what I envisioned but had the concepts behind them. I would undoubtedly have something to show other than plans by now. I'm human though so of course not all my decisions are based solely on logic. My stand on the extent I reach through concept has always made time spent on building lesser projects seem trivial. Working in a sandbox to experiment and having a sandbox within your mind may not seem the same to some but it is exactly how I've approached things. The time I mentioned was the furthest I could remember contributing anything towards what would later become concrete. I obviously spent time within that where things were nebulous at best and had hardly considered realistically developing any of it.
I'll start posting some of my concepts and such soon, it'll atleast be something to share.
