First of all I'd like to talk to you about some monstrous gaps that definitely need to get bridged in the upcoming game destiny. Also, to collaborate with the community to see if there is a way to fill those troublesome pitfalls.
Miltiplayer
First off I would like to see an enhanced multiplayer experience. One that opens up the playing field for huge gains while it can still grab the players attention with some minor challenges. Such challenges I'd like to see that are utterly much more vast and complex than regular ones, but they are still possible if you just apply some time and effort.
Map Editor
Secondly, a map editor would be another great addition to this franchise because it would allow the player to build, share, and improve architecture passed down throughout the community.
AI
Well as far as AI are concerned we really haven't ever seen them outside of a campaign scenario or a multiplayer one. This particular gap definitely needs some attention. Perhaps there is a possible way to include them in another form of the game without damaging it. A way to incorporate a single artificial intelligence without needing a huge reason why or why not it should be included.
Lastly, from these bridges listed above let me as well as others know what gaps you would like to see bridged in the future.
