Watching this trailer, I thought "Cool! A free roam superhero/villan game, a la Infamous (Which admittedly I haven't played, but am planning on. Eventually.)
Then I saw "Online". Then my thoughts turned to "This would be SUCH a great idea for a sandbox super game." I just imagine little touches, like throughout the game, the occasional scuffle between a hero and his nemesis, as you go from point A to B, and a variety of skill trees, either all available to you, or you pick one to upgrade, with a wider variety of powers, which can have some powers shared with other trees. ((Like an elemental master could use air to jet around quickly, as could a technological master, using actual jets.))
Anyways, that's just my random thoughts from a person that should really be in bed at this hour.
