God, I don't know whether it's just the sensitivity on the controller turned all the way up, but the ship movement looks super smooth. I'd love to see the space missions turn into this. They can keep the objectives in the current space missions (Take down fighters, escort fighters, take down turrets on capital ships), but missions themselves will feel much more dynamic.
My issue with the current on rails segments is that you can't tackle it at your own pace. Especially in the missions that task you with destroying parts of space stations, I find myself with 2 minutes of extra mission time, because I've all ready destroyed everything I needed to destroy.
During the space missions that have you go from start to finish killing a certain number of enemies, the action isn't intense or varied enough. It usually involves enemy fighters flying across your view, enemy fighters coming towards you, or capital ships floating in the distance. And that's about it. The on rails missions in Starfox were faar more interesting.
I'd love to see open space missions that involve they're own tiers of gear, like in PvP, but that's too ambitious. I'm not asking for a flight simulator, just something like the video posted above. They don't even have to remove the on rails sequences.
