I think they were pushing it a bit asking for £300,000 to be honest, especially when Godus, which is being made by a very high profile industry figure, was barely on track itself... in the end it didn't get much more than their asking amount of £450,000 (and they're arguably the same genre of game with the same target audience).
That said, I sincerely hope this sees the light of day (I'm sure it will) as it looks fantastic! I'll definitely be backing it again if it reappears with a lower goal.
