I was thinking that a multi map tourney would be a lot of fun and challenge players differently.
If you win the first map, the second map will load randomly or predetermined for the second game, and change again for the third....
I could see it as predetermined maps or totally random.
I don't see how it is possible to do with the current set up, but I think it would not be very difficult to add the feature.
The single map tournament can get boring and also makes it tough when some people are very familiar with one map. It can even the playing field.

Seems like a fun idea. Post it on Uservoice.

I'm sure this idea has been brought up before. Maybe you check uservioce first before you create a new one. No idea how you can filter it tough

you could do it via CLOT, but what do you mean by 'win' the map? Would these be single player scenarios made up? Or would you face another player in the next 'stage'?

My Idea is for tournaments. First game is one map, winner plays the net map, Loser pounds sand.
