The most time consuming and difficult aspect of these battles is thinking of a theme and trying to establish wether it would appeal to a majority of entrants. And you guys just show how difficult it can be. At one hand nub says that generalizing waters it down and Zipfinator says that if you keep it generic, it can go in more directions. And if you go back in this thread, you see the same discussion over again (that's not a bad thing though, it gives me good insight into what people want). But it's very difficult to find that spot somewhere in the middle.
F.i. the port battle: I took some old suggestions, such as wet, underwater, pool. And started thinking about how I could make that a bit more specific, but with enough freedom to expand on it. I first landed on 'wetlands', but that is very limiting and not unfamiliar in the HL2 universe, so as far as I'm concerned that was a no go. At that point I was already thinking about going an entirely different direction. Then someone suggested docks, which in turn made me think of port, which fit in to my original thought of water, while being broad enough to become a nice cosy little town, or an immense port like Rotterdam. And it even allowed expansion into air & space.
The difficulty is, that I can't really tell if the theme will be received well, until I post it
