&gt; their own private code framework that is too complicated for anyone else to make use of<p>Well, to be fair, games are one place where code reuse and maintenance by third parties is less likely to be needed. The real sadness is when you get corporate websites, technology platforms, and the like that decide they need their own framework to make their own set of tradeoffs, and do a mediocre job of it, and end up with a slow buggy bastardization with 15% of the capabilities of a common well-understood framework. If I had a dollar for every minute I wasted on something like that... it&#x27;d be an accurate description of a nontrivial portion of my career :b<p>Bonus points for making this framework to optimize performance, without actually measuring the performance or setting explicit goals.
