By my (admittedly idiosyncratic) standards, I'd say roughly half of the entries I categorized as flawed in some significant way and not a threat to win. This was not usually based on looking at the rules, although I did read through some of them. The problems included very crude art, very crude or simplistic design, poorly-written or incomplete descriptions, or other reasons.
My easy dismissal of these might be wrong - there could be a gem of gameplay in there, hidden behind bad art, in the same way that visually beautiful games can often suck in terms of gameplay. About 1/4 of the games had good to great art. My art isn't the greatest, but it's OK, and the game behind it is fun. I'm not certain the rules will make it clear how fun it is, and there are some complexities that I'm not sure I got across. The fact that I'm competing with six other space-trading games is troubling, too.
Well, we'll see how it goes. As usual, I'm sure I'm over-thinking this.
