Please, do not put more forge maps into multiplayer in Halo 4. I miss how Halo 2 had fewer maps that were all well thought out and developed. They had color other than grey and blue.
If there is a great forge map, get permission to remake it, and make it well. There should not be new maps every week. Make them something that will build up excitement and worth my money. Charging for boring maps with no thought just makes it seem like you are milking the name.
Also, bring back the number ranking system. I want people to see my rank by how good or bad I am, not how much I play.
