Cons
Con The developers do not actively communicate with the community
Not only have the developers driven the community away, they have actively closed the forum.
News articles have not had any changes since 2016, and the last news article still has links to the now removed forum.
Con Windows-only
NeoAxis Engine is Windows-only.
Con No community
As of 2016, the creator has completely destroyed his own community in order to silence any criticism from developers.
Con Lack of tutorials
Unfortunately, the wiki doesn't contain many programming tutorials, and the source code itself isn't very self-documented. Creating new gamemodes or AI will require lot of research for beginners.
