RE: Designing a renderer

(And with little effort, Jamie and myself bring us back to game design, sort
of)

Yes, one of the problems hobby projects have is the lack of proffesionalism.
Normally there is no game design, there is no goal, and thus no completion.
The other type of hobby projects that fail (Like a lot of my own) are
because they are too grand in scope, so even if they have a very well
written design (game design I mean) they never get done.

Thus the IOTDs on flipcode which are "I finished my first game, it's a
bomberman/tetris/quake clone" impress me way more than "I implemented an
engine with the following list of buzzwords". Ofcourse each case is
differant.

So when asked how to get into the industry, I tell them to design(see:)) a
simple game and make it, from start to end, make sure it's finished, that
will impress your potential employers more :)
