Pros
I worked at GameSalad for nearly 3 years. It was a great job, with great people. Hours were good, pay was good, benefits were good. However... see "cons".
Cons
The CEO is poison. All he cares about is flipping the company. He was only brought on because he did it once before, but it's obvious he has no clue about the games industry, the tools industry, or the education industry, and that he's floundering and destroying the company in the process.
The company has no financial vision and no clear route to revenue. They've gone through 5+ business models (and that's being conservative). There was a LOT of infighting at the top until the CEO basically fired or forced out everyone, including two founders, the COO, the CTO, and most of the directors and production staff. There were two surprise rounds of layoffs, and then basically most of the decent employees left after that.
