Hehe, ok. Let me get one thing straight here:
At the moment we are not in a desperate seek of a new game mode. You guys can of course post some ideas that you had but try to relate it to existing things in SSGX. Or keep the concept simple and fun. You guys remember the Skyscraper mode of "Destruction Derby RAW"? This was a very simple yet great mode to have some fun in between of serious campaign races. It would be good if a new game mode does not contain completely new weapons and mechanics but rather use what is already there. "Fatal Inertia" has the Magnet Mayhem mode... Basically a weapon pad to spawn only one certain weapon.
Of course, a new game mode can be close to existing modes, it can also be totally different visually [like Zone in WipEout] or it can have another goal than completing laps. I for example once had the idea of a game mode where the ships are in an area. Everybody who leaves the area looses. And there are weapon pads that only spawn Impulses... Of course this is just a very flat concept and there is no need to develop on it, but to give you some idea of what we are looking for.
