SW.Republic Commando was a great game, but EU is EU.
Yeah, not to mention that it takes place in the Clone War era, which means things could have changed since then. It could very well be that the practice of cloning out of perfect soldiers fell out of use, perhaps because it was too expensive so that by the time ANH rolls around, the Empire is using soldiers that aren't as well trained as they should be, but as compensation maybe have larger numbers of them. Which begs the question, what exactly did happen to the clone troopers after the war was over? Is there any point of transition where the Empire starts looking more like the Empire in ANH compared to that of the Clone Wars? Everything looks so different between the two, with a few exceptions.
