Add the winter classic or stadium series

The thing with the Winter Classic is that it's a lot of licensing and a huge amount of work to accurately model the arena for what is essentially a one and done playthrough for most everyone. I would be surprised to find out that that there were people that played this over and over again when we had it. It's a huge expense and a ton of resources and time. So, we can choose to work on a feature like that or make a much better use of those resources and that time to add features and make improvements that benefit the community as a whole and applies to a much bigger part of the game.

It would be awesome to have this. Don't get me wrong. It's just a huge amount of work for something that doesn't get used much so it makes more sense to work on more highly requested changes or things that apply to the whole game instead of just one small part of it.
