While I do certainly think that python engines are well worth considering, I think that looking into other options would be worthwhile.

I've tried messing around in python game engines, pygame specifically, in the past. Much like kivvy, despite no real performance requirents, the programming felt complicated and confusing. While I do think that the merit afforded by the learnability and readability of python are considerable, I think that the structure of the packages might be more confusing than they are worth.

Another point that I think other engines have over python ones are popularity. While trying to learn and debug issues that I had in pygame, I noticed a significant lack of stack overflow pages. This is likely due to the unpopularity of python as a choice for making real games in. I think that the active communities around engines like unity and godot, and the thousands of hours of video tutorials that result from that popularity, might make them even easier to learn than pygame, despite the more complicated language.

Of note, i have VERY little experience with game dev, so I don't know what I'm talking about. More opinions should definately be consulted and more research should definitely be done before deciding on an engine for such a time-intensive project.
