Ok, here's the rationale - the amusement park was... amusing. Makes me smile :-). The Island looks like a pleasant little game, and the map is enough to add a geographic component to a concept that would otherwise be a repetitious circle. Nice. And the Lohan map is cool - if I study what you have the game will make sense, no doubt.
But SteamBlitz (yclept early Steampunk Risk and corrected inline)... dude, that's a game I'd buy. The map would sell me, the details would clinch it. A publisher would no doubt insist on a bunch of playtesting to ensure it is balanced and interesting from first roll to last, but as far as I'm concerned you have a winner. If the rules and details are intended to simulate a game rather than play well as one... <shrug> the contest was to make a map for a game, not to make a game that has a map; subtle difference :-).
And I want that bicycle with a machine gun. Currently I dare not commute down the five miles of busy highway between home and office, otherwise a doable distance. If the hurtling ingots of chrome-edged doom had a little respect for the two-wheelers, maybe it would be a survivable trek.
