I'm sure this has been suggested before, but since in another topic Lopdo said he'd like to add some features after games have ended (e.g. graph of how game went, replay feature), I'd like to ask for a simple one:
It'd be nice if chat stayed open after the game had ended. I know there's not much to say, but it'd be nice to have a chance to be all "good game" or "well done" when the game was finished.
I think one of the big problems with Vortex Wars is that there's no sense of community, people have no qualms about being an arsehole or constantly backstabbing. It's actually good tactics. Just not as much fun. I think any small changes to encourage a community spirit would be good.
