The Unconventional Game Engine Jam is a game jam where it is not allowed to use certain game engines.

You can use any game engine you want, as long as it is not present in this list:

  • Unity
  • Unreal Engine
  • GameMaker Studio
  • RPGMaker
  • RenPy
  • Godot
  • Cocos
  • MonoGame
  • Construct
  • ClickTeamFusion

This list has been determined by taking the top 10 game engines used for games available on Steam, according to SteamDB.

As a game developer, the Unconventional Game Engine Jam is a great way to learn a new tool, and work with its own tooling and constraints. It is a great way to learn and gain experience on the capacity  to adapt to new tools, and with its length of one week, you will have enough time to understand the tool to make a great game!

And as a game engine developer,  this game jam will allow you to use your own game engine to create a game with a given theme, this is a precious experience needed to understand what needs to be improved on your game engine. You can find people that have no experience on your game engine to make a team, where they can ask you questions about your tool and you can get real world experience on what it is like to use it.

You can present your own game engine in the message board, where game developers can pick it to use it for this game jam.

Where can I find a game engine?

If you don't know what game engine to use, you can take a look in this game jam's message board, where game engine developers will present their own engines, look at SteamDB's listing, pick a game you like that you know uses an unconventional game engine and use it, if it is publicly available, or even make your own!
