I do that when I don't have time for a full match say before I gotta go to work or something. A game with quite the depth, and while you wouldn't be able to fit a whole match in during 30 mins, there are duel servers out there where you just 1v1 people and then people will organize 3v3 skirmishes and so on, all within the same map.obviously, if you don't play on vanilla lul.
