One of the reasons for the success of many 90s/00s games was the ability for the community to make and distribute their own maps (the UT series in particular). What would be the best way to allow community map-makers for a game where maps are small and discrete, like with an arena shooter? If players downloaded the Unreal Engine would they be able to load up your game and make maps for it in the editor? Would you need to create an in-game level editor from scratch?
Thanks in advance.
