Hello John,
I wonder what motivated to move the team to C++ for idtech4.
Fab
"
"
There was a sense of inevitability to it at that point, but only about half the programmers really had C++ background in the beginning. I had C and Objective-C background, and I sort of "slid into C++" by just looking at the code that the C++ guys were writing. In hindsight, I wish I had budgeted the time to thoroughly research and explore the language before just starting to use it.
You may still be able to tell that the renderer code was largely developed in C, then sort of skinned into C++.
Today, I do firmly believe that C++ is the right language for large, multi-developer projects with critical performance requirements, and Tech 5 is a lot better off for the Doom 3 experience.

"
Is C++ a better language for developing games than C? Today, most games are developed in C++, and I know that Doom 3 was developed in C++. Having worked with both C and C++ for quite a while, do you think C++ is really a better language for developing games?"
"
Yes, it is. I'm not a fan of the more complex features of C++, but grouping things into classes is a Good Thing.
