Post any questions or helpful links/topics here the pertain to a specific game engine.
Might it be an idea to have subcategories for the common engines?
Idk why I just saw this so I apologize for such a late answer. To answer your question we cant. Discourse only allows categories that go 2 levels deep so we would have to have a separate category for each engine under project help and that get out of hand really quick.
Instead we have tags that can be used to mark what engine the topic applies to. You can find a list of current engine tags under the engine category here: Weight Gaming
If there is an engine missing you think should be on there feel free to request us to add it.
