I got a job in the games industry because I knew someone. It's such a tiny industry everyone knows each other so just turn up to things a talk to people.
Personally, I agree with Metalhandkerchief. Just because people play games doesn't mean they will be good at making games. Its long hours for poor pay. It will also destroy your love of other games because all you will be able to see are the flaws. If you can get past that then you will enjoy it.
I also don't understand why become a designer? 99.99% of a designers time is working on already nailed projects and your ideas will never make a game unless you go indie/do-it-yourself. There are a wealth of jobs - programmers (network, gameplay, audio, front end/UI, etc), artists (Front end, character, environment, concept, etc), producer. Then you have all the people that make the studio run like admin, IT, finance, etc.
I guess it's like the CSI effect on the UK forensic job market. There just ain't enough job people!!!
