They (as in Microsoft) would never allow that to happen, its sort of like how if you enable mods in a game they disable achievements, like just imagine how stupid it would be if that were the case? Everybody would just make 5 second hives lol.
Halo’s forge is a great example of game with an awesome map maker, it started off as a map editor in Bungie’s mind but over time they warmed up to it and made it a really solid map maker, 343i (current Halo devs) only expanded upon it over the years.
When you think about it TC screwed the pooch with this one, a good map editor (not even something as sophisticated as the one the devs use) would be wonderful, instead of everybody just holding onto their seats waiting for whatever scraps TC feeds us each operation we could just make our own awesome maps, and not gonna lie they could be lazy and instead of actually making new maps they could just focus on giving us tools and new assets and etc. over time.
I’m aware that you are sort of thinking of a dev kit, although that makes sense I want to stress that a gamer friendly and easyish-to-use map editor/maker would be much more impactful, like one of the main requests from Skyrim modders is that it would be cool if there was a beginner set or something that an average joe can pick up and learn how to make dungeons or NPC’s in etc.
Just to articulate how I feel about this; Forge has been more impactful to Halo then Horde has been to Gears, let that sink in.
Edit: about Pahanu, if Gears of War didn’t become a lancer centric game (with 5 stacks, and ranking system, and etc. exacerbating it) then the map would be much much more popular, same reason why if you go back and look at Gears 2 maps there is no question that a lot of them would be extremely unpopular in Gears 5, like you look at River for example and its a horror to think of the spawn traps/setups/camping that would go on in that map in Gears 5’s climate. Pahanu was about a decade too late I’m afraid.
