I really just want a free roam/endless mode
By far the thing I want the most for AOT3 is to be able to pick certain areas like Trost, Shiganshina, the forests, really anywhere with swingable terrain, and just be able to swing and kill titans infinitely.
Part of the reason I go back to AOT2 is because I like to decompress if my work day was stressful and just want to swing and kill a bunch of titans, but I HATE how it limits you to however much are in the mission and also spawns in those big yellow-y titans at the end that kinda just feel tedious to do.
Ideally, we would pick the endless mode on the menu or through a training option. Then we could toggle the blade and gas canister meters and if NPC’s are with us. The same way a lot of people like to swing around in the Spiderman games, this would literally be an Attack on Titan version of it. A 10 year old ROBLOX game did it I’m sure it’s possible here too
