I suggest a Unit showcase option where you can see all the units in high quality model. It would be great to know how a unit in a RTS game is from near, or inside or as a very high model. Usually during the game you have no time to zoom and have a close look at the unit. I also suggest that besides the High quality physical units, the user should also be able to see the units properties(like the weapon he use, or the armor, etc), or maybe even his story. Someone may say that this is what they usually present in the website but i would like to see it in the game. I think FB2 has the capacity to show a high quality unit not during the game but as an option in the main interface.
