I don't really know Chris Metzen's work that well, outside Starcraft I have no idea what other projects he worked on (Diablo, Warcraft?), and I am not going to say that his Starcraft work was utterly brilliant as the 'inspiration' seeped rather through (I have no doubt that admiral DuGalle takes inspiration from Star Wars' admiral Thrawn, brilliant admiral who with little resources and unconventional thinking is able to take out superior forces), but it was still serviceable and could be expanded on. Starcraft 2 much like the later Mass Effect games seems to have dismantled its own world/setting with all these changes and retcons. Perhaps Metzen was indeed better when he had to prove himself. BTW, had he not announced that he was going to retire?
