Halo 5's Forge is definitely the best in the franchise, but that's the best thing Halo 5 has going for it, unfortunately
I hope Halo 6 will be a return to the Halo we once knew and loved, 343i did say that the Spartans won't look like Power Rangers and that there will be split screen in any new Halo game that comes after 5 at least, i just hope the game itself turns out better than 4 and 5 have
343i has A LOT of stuff to explain, connect, adjust, and probably even remove some things here and there, they're probably gonna have a lot more books and such for all that and save the bigger stuff for Halo 6, but i just wonder if they'll actually be able to pull it off AND make a Halo game that won't disappoint people, probably for the last time, seeing as people have said that they lost faith in 343i right after Halo 4, and especially after 5
