There isn't much I'd like more than to see Star Citizen implement FPS planetary combat but, as others have said, it strikes me as an incredibly ambitious goal. I appreciate that the CryEngine is built around FPS combat but it will still require a lot in terms of art assets, level design and gameplay design. How are they going to ensure there will be enough other players on the planet to make it interesting? I just don't want it to distract from the core mechanics.
I really hope they nail the gameplay in this and there is certainly a lot of potential given the amount of thought being put into it and the community participation. This is the game I've been waiting for since playing the original Tie Fighter nearly twenty years ago and Starlancer (another Chris Roberts' game) over thirteen years ago.
