Excitement Over New Ideas

So, I wrote out a really basic story for a game last night, and it's been running amok in my skull ever since. There's a real kind of "woot!" excitement behind a new idea. My responsibility is now to not allow it to run away with me - I don't want to over complicate it to the point where I couldn't complete the project (mostly) solo. Still, I'm in that zone where ideas keep flying at me out of the blue as my brain digests the overall concept. I suppose the best thing to do is write them all down and sort 'em out later? Kind of like writing... pour everything out in the first round, and clip, snip, cut away at it until it's actually good.

Alright, off to work...
