I've been working in the industry for years. I've worked for Ubisoft, Atari, Bioware, Lucasarts, Jowood and a few others.
What I can tell you is that it is far from a walk in the park.
Long hours, low pay, no benefits, forget your friends and any girlfriend/boyfriend or even your familly.
This job will consume you like the fires of hell.
Until you get out of QA, then it's more like Hell's lobby. Still hot, but not ''melt your skin'' hot.
Have you ever wanted to work 10-12 hours a day, 7 days a week for two years? Welcome to QA!
If you can get through that initial ''bottom of the barrel'' stage (pun intended) , an essential part I think to making it in the industry, you are ready for game dev.
