Over the years I've played with a few game testers. One in particular was part of our Left 4 Dead crew.
I told him when I was younger I wanted to do what he did, and I just didn't pursue it cause others told me just to avoid that job. Well he said they were saving me a headache. He's like picture this, you get to work, you get your coffee and turn on your pc. You sit there and load up the game and it crashes. So from there you get the log and send it in to the programmers and wait for them to fix that issue, but while you do you have keep trying to get the game to run. Everytime you had an issue it would be logged and sent.
Finally they fix the issue and the game boots up and going to the main menu. You finally have a game that loads and click to go to the next menu or start the game...... it crashes. So again you get the log and send it away waiting for it to be fixed, but while you do you have to keep loading the game and try to get it going, over and over and over.
Now finally the game gets past the main menu and loads into the game. Finally happy you push your controller to walk forward and it crashes. It crashes when ya move left, right, back, hit any button, but maybe it won't crash when ya hit start.
This goes on all day, everyday till the game starts to get ironed out. Over and over and over, for months on end and as time goes on it drives ya bonkers. They fix the crashing that happens when ya move all around, push most buttons, but now the start button push that worked before now causes the game to crash. Guess what happens next. This all could go on for months. Load your pc for it to crash, all day, everyday. It's not a job for everyone.
He loved and hated his job, not just because of how much that part of the job could get more then annoying, but also cause of the content he'd see not make it into games. He said bad decisions would be made to remove something great in a game for something that wasn't even close to being as good as what was removed or they had to cut it for reasons of time. I still remember him saying for how much you loved Warhammer Space Marine, you would hate it if you had seen what was cut. It always made him bummed knowing how much better that game could of been.
He also told me about Mr. Toots, one of the greatest weapons in video game history.
If anyone is looking at getting into this field, don't let this post scare ya off, you may love the job, just be aware it's not all fun and games.
