Very nice. I think there should be some sort of hud for when you're in the 3rd person mode though... That's how I always played the other games in the series... (2,3, and the Reneviction & Evochron demos, which unfortunatly I all sucked at, despite how fun they were)
I love how the planets in this one really feel like planets, although they still could use a lot of work once you're on them if you ever plan to put more emphasis on planet exploration. Overal really good though. The graphics in Arvok are like next gen compared to Evochron, although cosidering you pulled all this off in dbc, you should definitly go pro. I bet you could make something that really was completely next gen if you did.
If I didn't completely suck at space sims, I'd buy this right away. As it is, if I get better at them anytime soon, I'll definitly be buying this.
