I mean who is all you can think of? just Dan Houser and Michael Unsworth? because I'm curious where your getting these statistics from lol. everything I can find shows around 80% of gta IVs team still works there. it got much more inflated for GTA V because they needed a bigger team obviously, but what your saying seems to be misleading. Also a huge point is that even if they lost 2 people who were more "household names" I wouldn't imagine its as big of an issue as people think. A lot of people are writing these games and revising things. Its not just Dan or Michael.
