I know that we’re really far from eventlab 3.0, but i want you to think about my ideas for eventlab 3.0.
When i saw forge mode (halo infinite) and unreal editor for fortnite (fortnite), i told myself that if eventlab 3.0 had features like: adding animations, building custom prefabs, adding custom audio and music, importing files, A.I tools and other feature similar to forge and UEFN, i can only imagine the great community creations in forza horizon. If the give us advanced tools and make eventlab 3.0 a game engine for itself, than we can expect great and 
things to come.
Right now there are great games running in both halo and fortnite such as halo battle royal pvpve & lego fortnite & etc. If eventlab 3.0 gave us the freedom we need, then we can make our own maps, games, remaking FM circuits and maybe … our own forza horizon festival!
