There is no such thing as "a simple game idea". Well, there is, but it's called "genre".
Anything more detailed is a design document. A skeleton to grow some flesh on. A game in the making.
> What stopped you?
Extremely bad user guides, first and foremost. But it's an industry-wide problem, not gamedev specific one.
People grab game engines to do what they want to do, not to acquire redundant knowledge about computer's resource management
(it's supposed to be handled by engine, there's no advantage in using engine over raw programming language otherwise)
or programming concepts
(aint it supposed to be handled by engine? Once again, there's no advantage of such engine over raw programming language otherwise).
And guides tend to mull over same low-level stuff no novice is ever interested in.
> What tools do you currently use?
Default Python 3.x bundled with Bodhi Linux. With some effort, it can do most things GoDot can in 2D.
