I did this once, either in 2K13 or 2K12. It was the worst basketball gaming experience of my life. I decided I'd like to try to earn every achievement in a 2K game and even though I despise online play, I decided to give it a couple days worth of run so I could try to get the five in a row achievement.
I spent the entire time stressing about whether my game would connect, whether my opponent would play like he was four years old, whether my opponent would quit once I started winning, and whether maybe I was using cheap tactics myself. The fifth consecutive was stressful only because I couldn't stand the idea of having to play at least five more games online.
I'll always remember one of my losses being to someone using the '96 Sonics. Anytime I'd score he'd throw a 70 foot inbound bomb to Shawn Kemp. Then he'd just push toward the basket and he'd slide past my defenders and dunk. He scored something like 64 points with Kemp alone.
And I don't mean all of this as a condemnation of 2K or something. The five in a row comment just reminded me of awful times. There were other online achievements to earn but at that point, it just wasn't worth it.
