I trust in a company and follow a company loyally until I've been screwed over. I play games by Bioware, Blizzard, the former Westwood, former Troika, and the former Black Isle/Interplay which happens to have some of their ex employees working for Obsidian who I now follow.
If a company has the talent and the good reputation for making good games than I will follow that company or it's well known employees if the company breaks up.
