Victory, you say?
On the issue of simulator versus arcade...I know that Wing Commander is not a realistic simulator, the way that many flight simulators are. I am aware that its physics are not accurate. But you're taking my response too literally. Wing Commander was the first (or one of the first...maybe X-wing predated it?) of the "space combat simulators". It's distinct from arcade style shooters in that (1) you control where exactly your ship goes, whereas traditional arcade shooters have a fixed path you traverse while things fly at you and all you do is decide where to aim, what to shoot, and where to dodge, and (2) you have full 3D maneuvering capability, instead of moving in a plane (as Arena will apparently make you do).
Wing Commander was released first. The point you present was very much relevant in the early 90's. Not so much today. In relation to Galaga, WC was really a space simulator. Today, a Space Simulator would be a really boring game. That said, even tought it might look differently, Arena has much more to do with Wing Commander than Space Invaders in terms of gameplay.
