The top game on Steam for many months now is PlayerUnknown's Battlegrounds. It has a "mixed" rating, with only 49% of reviews giving it a thumbs up -- by far the lowest rating of any game in the top 20. The reviews tell a story of how bugs, lag, broken servers, loot crates, and rampant cheating add up to a barely-playable game.
And yet, no one cares! It continues to top the charts, both in sales and cumulative play time. If we think about why that is, we might come up with non-monopoly explanations for why buggy software proliferates in other fields.
It can top charts and have also tuned away a sizeable portion of the potential player base. Both can be true at the same exact time.
You're telling an easy to believe just-so story. And that's the problem with the way these things are analyzed.
In markets where individuals do make the software choice, buggy and slow products are often punished. You see a lot of warnings about bugs and performance problems on video game reviews, and those reviews do seem to hurt the sales.
