Why I Roll My Own
I use my own custom game engine for my projects.That's right. I am not using Unity, Unreal, or any other packaged game engine.
There are a number of reasons why I chose to do this. My most common answer is "Because it's fun!". I only work on my projects on Saturdays. That means my development is really slow, and it's going to take a long time for me to finish anything. I expected to spend years of my Saturdays working on a project before it's finished. I realized pretty early on that if I wasn't having fun on those Saturdays, then I would probably end up quitting before anything was ever completed. Also, I really like programming. It's much more enjoyable for me to make my own code then to use somebody else'.
To date, I have spent about 255 Saturdays working on the Strategy Game in one form or another. One more Saturday, and some might just roll over and quit. Luckily I have more capacity then that. I can happily say that I am still having fun and I look forward to next weekend.
