I think we should have either of these two options below.
1) Have a maximum number of troops per territory.
2) Have a maximum number of troops per player.
This way the games would in a sense go quicker but also it would keep from people stacking up hundreds of troops or at least a lot of them on one place or something to that sense. Plus the real risk board game has a limit on 12 troops per territory. Now I think you should be able to set the number at like 10 but all the way to like 50 so that it is a much simpler game.
