I'd love to play this game if it turned out to be fluid enough and popular enough to make it a huge title. But I have seen (and played) so many games over the years that have boasted new features and game changing mechanics that didn't make it that I'm sceptical about new ones. I would still like to see new games like this be a hit because it changes the tried and tested formula that frankly, a lot of people are becoming bored with. Shadowrun is a case in point, it was a good formula that ran aground because they focused too much on the magic side and trying to make it "revolutionary" that they missed the biggest aspect of an FPS, the shooting, which was clunky and awkward. And these sorts of games that have had huge potential have missed the point so much that they have gone from a huge excitement to a massive disappointment. And in turn this makes these sorts of games less popular to the mainstream that the few good ones never get noticed, and thus don't get the popularity they deserve.
But I do hope something comes a long soon and changes the formula a bit, because I personally am fed up of watching people (myself included) playing Call of Duty 4 (which was a great addition to the series and the last fresh thing to happen in the call of duty series in my opinion) with a new name every year for the past 3 years.
Looks like a great game! Can't wait to try it
