True, but I don't think it's really relevant, just a nice anecdote. ID was one company, many many amazing, award winning games were developed on other platforms, yet we don't impart any kind of magical powers of productivity to them. When I was going to college, many labs had NeXTs, SGI workstations, or another Unix variant. It's very likely people who were of the same generation would gravitate towards those development environments when they left. The NeXT's strengths, like Interface Builder and Objective-C didn't really apply to DOOM for example.
