I am not sure what you are talking about? The CGI is very cheap, there is a reason why they waited until the 6th episode to have grunts and jackals on the battlefield; they were doing it to save money; which explains why the Elites until then look ugly.
Well, the series didn't need to follow the game to be good by using the names of characters and casting people who have no physical resemblance, personality resemblance, or occupation resemblance they are simply drawing attention to the difference and encouraging the negative comparisons.
At the end of the day, we live in a world where decent 1080p cameras are $50; crisp cinematography is a really low bar to meet, especially considering the millions Paramount spent.
