Rolling your own is mostly a fixed cost endeavour. Taking 3.4x more time on a week long project isn't that bad when considering that most projects takes years.

Rolling your own is mostly a fixed cost endeavour. Taking 3.4x more time on a week long project isn't that bad when considering that most projects takes years. And then you have to consider that the guy got 10x the performance on his hand rolled project, getting unity to similar levels of performance would likely take way longer than just using his own engine. > Yet, I've witnessed far more game projects die (especially by beginners) that went the handcrafted all-the-way route versus people using game engines. If you don't have the skills required to make your own game engine then you shouldn't do it. You shouldn't learn how to make a game and how to make a game engine at the same time.
