It would be nice to have something new and difference that won't affect the way we use the game unlike how most developers change there games so much leaving alot of unsatisfied users these days.
I'm sure there a lot of people that might have some good ideas to improve this game a little more.
One of my ideas are custom characters that are viewable online without the need of any kind of hack or mod just like in UT2004. Not only will character making activity rise but this may as well leave less work for the developer to do that roll or even get more people motivated for being creative with modelling characters of their own.
If it's possible drivable vehicles that can be edited and customized in game and usable online as well.
Maybe a new game mode can be added like little race for an example.
Those are just my suggestions. For all I know that might leave alot of work for the developer to make all that happen unless he gets help from other developers. In other words this is unlikely to happen and it's yet another bad idea [v.v]
