My initial thoughts were NOOOO it's a flash site!!
But actually that's one of the best flash sites i've seen! It's very nicely done, very clean and easy to use.
I generally hate flash sites because the designers go off on one and try and do things that flash allows you to do which are pretty cool but completely pointless for a website and makes the site very hard to use and clickable items sometimes impossible to see.
The main problem sites are those for upcoming films... they always have a stupid interactive flash website and are just terribly hard to use and take AGES to load... I think the website for the Jericho game was one of worst i've seen because it had a nice spooky scene laid out in front of you but the buttons were hidden amongst the scene so you had to hover your mouse over every square inch of the screen just to find the things that you could click on... And i don't think they were particularly meant to be hidden...
Anyway, the power quest website looks awesome so congratulations to the person who did it!
