Why do people complain so much about certain video game studios and publishers? Do you play games from a wide variety of different publishers?

It feels like everywhere I go online, people are griping about this or that developer and that they don't enjoy their games. So out of curiosity, I went back through my games list on the PSN for every non-sports game I've played since they started tracking things on the PS3.

I've played games produced by 35 different studios, but more than two games from just six! Square and Ubisoft, who often get a lot of grief, are at the top of my list, followed by Traveler's Tales (all Lego games), Bioware (Dragon Age and Mass Effect), Naughty Dog (all Uncharted) and Polyphony Digital (Gran Turismo).

There is no other studio who I've played more than two games from in the last 18 years or so. Lots with two games I've tried, but none with more.
