It looks like a great deal of effort has been put in that game, it is visible on the screen.
The video is a bit confusing though. It shows gameplay, sure, but the first thing you choose to show is the possibility to get drunk and some kind of duke nukem like scene in the toilet ^^
Is that a major feature, or more like an easter egg ?
It may have been shown a bit later in the vid, focusing first on the gameplay features.
And those appears a bit confusing too. I mean, the fight, with all the command screen, the minimap with blinking dots. On video, it is confusing to me.
This video intrigates me more than it presents me the game clearly.
I'd be curious to play it, if there was a demo, or visit an explaining website.
But, as far as I'm concerned, this video does not make me want to play it "more than that".
I'm like "it looks nice, but what the heck is going on ?"
Again, it looks quite nice and polished. The providing of exploration (top view) and combat (plane) is intriguing. But I'm a bit "left hung". :)
Edit: Oh and very nice effort on the audio. The soundtrack is quite immersive, voices and fx well rendered.
