Over 13 years have passed now since the release of Knee-Deep in ZDoom. Looking back and having the same experience that I have now, I would have done a few little things in a different way. But as it is with a lot of decisions in my life, I tend to not regret any of them. Making a decision involves including every relevant factor in this particular moment. You can't know every aspect of its consequences but you try to make a reasonable choice according the circumstances. And that's why every decision is right in the first place because you simply do not know any better. When time has passed you can only tell if it was a good decision or a bad decision.
