I think OO programming is something a lot of us do within a procedural context without even knowing it. Before I'd even heard of OO development, I was implementing what I know now as virtual functions for my objects, in assembler on the Amiga. I think with games, after doing a few you soon realise that things fall into this paradigm easily and you tend to move in that path without knowing it. Having a language with this constructs built in, makes the job easier to implement. OO languages are just a tool for OO development, they aren't OO development in and of themselves.
