How should the engine and project code be licensed?

[Net5F]

This engine is currently AGPL licensed because I'm worried about a future where some studio takes this engine, dumps more money than anyone else into closed-source development on it, then releases a high-quality world that vacuums up all the players. This type of monopolizing is, in my opinion, the cause of the current stagnation in virtual worlds. I would hate to see my work used as such. The downside of this is that it effectively restricts the engine to use by hobbyists (not the worst thing in the world).

I've recently started opening up to the idea of a more permissive license, but I require more opinions and conversation before making a choice. Maybe the presence of the engine would facilitate enough competition that the monopolization that I'm worried about isn't likely. I could be convinced, in that case, to switch to something like an MIT license.
