Incredibly boring, yes. What you do is exhaustively go through every option at every point in play, and verify it does the expected thing. Then you get a new version with fixes/improvements, and do it all over again. You learn to hate every moment doing this.
The dorm in college had a pinball machine, the old mechanical contraptions before LEDs took over. I was fascinated by them, but had no money, so playing them was a rare treat (10 cents a game, 25 for 3 games). One day, the coin op broke, and free games galore. Yay!
After playing that continuously for hours, something broke in me, and I just couldn't stand playing pinball anymore.
I honestly cannot fathom people managing to spend their lives playing video games.
The same thing happened to me with fireworks. I grew up fascinated by fireworks, and would blow every penny on them on the 4th. One day, in college, I had enough cash to buy all I wanted. I bought a lot. Went out to a field, and started lighting and throwing the black cats one by one. Bang, bang, bang. Some hours went by, again something broke. I haven't bought fireworks since. I have no interest in firework displays. The needle doesn't even move.
Go figure.
Never lost my interest in muscle cars, though :-) I grin like an idiot when I drive mine.
