Yeah don't end up like me with a folder full of library code, "tests", "prototypes" and a dozen implementations of the Tiled API but no game.

For certain personality types I think making an engine can make it very easy to get distracted and wind up in the weeds of something you don't actually need, overoptimizing, fence-painting etc. Using an engine can help with self-discipline and focus on the end rather than the means, although then you need to make sure you don't just wind up with a ton of mostly finished tutorial projects and no game.
