Curiosity, as a new person here... just tryin to learn about the trends and factor in Halo 5's scenario- it was a game that did good selling, but was also had Modern Warfare, Battlefront, Fall Out, and now has more competition this holiday season. So, Halo 5 already has an established community w/o the new Forge update- do you think the update will increase the community the same way Halo Reach did after Halo 3, or do you think that this non-launch forge system can only do SO well.
If by community, you mean forge community, then I think the community can only grow after what forge offered in h4 and MCC. That being said, a big part of the forge community deals in custom game options, so as I see growth for competitive maps and creators, we will have to see when it comes to wacky maps and modes. If you mean the halo community as a whole, I think forge could plug some wholes in a leaking ship. If we see a spike in population and community participation outside of the forge community it will be because of holiday sales, but I doubt it will be specifically linked to the December update.
