I think Irregardless meant that this is a job that a lot of people dream about having when they are children. Landing such a job as an adult would serve to realize that dream. This makes it pretty devastating if the job turns out to be a disaster.
I'm sure testing games is far more demanding and tedious than kids imagine it to be.
You might want to rephrase this then, your original wording comes off in a condescending "playing games? for money? he should be glad to have a job!" sort of tone to me.
Everything is more demanding and tedious than kids imagine it to be. :-)
