As a long-time Stardew Valley fan, I never thought I’d find a game that could capture my heart quite the same way. Fields of Mistria has done just that. I’m honestly blown away by how good this game is
note: just a random fan, have nothing to do with this game at all. It kinda saddens me that it hasn’t gotten as much attention though, there are so many mediocre games with soooo many reviews… this game is legit insane. it’s gorgeous!!
I could see that being a thing, but the line between the engine and the game itself is a bit blurry in this context. Copyrighting just the assets and content would often not be enough. There will always be a good chunk of game code which isn’t strictly part of the engine but under this model should remain closed source, otherwise people could just bring their own assets.
Frankly I’d be satisfied with companies open sourcing their games after they stop supporting and/or selling them, mostly for preservation and all that. I think that would be a great middle-ground.
Sure, depends on the engine, but very often there is a “scripting” part, be it quests, dialog, etc. and the where those scripting functions/library and language is implemented. The first are part of content, while the latter is part of the engine.
Also games have data tables, where the individual value for each record are part of content and the implementation of what each attribute does is implemented in the engine or some specific scripting.
Engines tent to have a clear split, because different kind of developers have different processes, and engines are often reused for multiple games.
IMO, that means that the whole game would be sources available (for the end user), while the central engine is open source.
This is just somewhat of a wishful thinking, not a requirement or whatever.
And sure, game devs releasing an engine/game as open source after they are done with it, would be great too. But I like to dream big ;)
