Hey man,
I’m in the same position as you, an aspiring Game Developer, and there are tons of things you can do to learn more about Breaking In, as well as preparing yourself.
I would suggest joining up with IGDA (International Game Developer’s Association) or at least join their forums. Their thread on Breaking Into the Industry was very helpful, and you can get some heavy useful critiques and blunt answers to your questions as well. Watch out for Tom Sloper though, he’s a scary prowler if you’re not careful how you ask questions, cause he’ll tear you a new one ;P!
The other great site that I use a lot is, www.gamecareerguide.com, they have a ton of feature articles written by Entry and Senior level developers, who have great advice for all fields. Not to mention, its directly linked to www.gamasutra.com, which is a great place to keep up to date with Gaming news.
And finally, I think every Game Developer has heard of www.sloperama.com in some shape, form, code snippet, doodle, etc… Another great site, and segmented in every various aspects of Game Development. The answers are concise, informative, and very enlightening to anyone interesting in the Game Industry.
For the most part, Tech-Artist.org is just a place where Technical Artists from the Industry hang out, and while I’m personally going for Level Design positions at the moment, its a neat place to hang out, listen and read their posts to learn and transition yourself into the Technical Artist environment, but from what I’ve read of your responses and questions, I think GameCareerGuide and IGDA.org are much better places to start searching for answers then here.
I hope this helps! I know how it feels, the Game Industry can be very intimidating and secretive sometimes, but look in the right places, and you’ll easily find a smooth cement filled path ;P. But for the most part, its up to you to do the work and research. =)
