I agree - I coudn't move the screen when I wanted to (yes, I found drag-zoom but find it clumsy), and adding that to the difficulty with working out who owns the units running around, and wondering what things like the light towers were for, I gave up after ten minutes. I just couldn't find a game in there.
On the upside, it performed well and looked great, so I'm looking forward to the next beta in the hope of it having a game in it!
