Some people are developing utilities to help players in their games. This includes things like saved game editors, fan-created modding tools, .ini file editors, adding Windows Store games as non-steam games and vice versa,... In essence, external tools that help players customize their games to their own tastes and liking.
What these utilities do is very much similar to mod development, which we already allow. They give players more options in how they want to play their game, whether they want to make themselves invincible, make their enemies harder, fix a bug with their saved game,... They're modifying existing games to either add new content or change existing content.
With this in mind, should we allow questions related to development of game related utilities?
