That's clearly not what am I saying. This would be a pretty stupid argument to make, since we've already seen this type of system work in more than one game. My argument is that I prefer a more logical system that is more internally consistent. Fallout New Vegas is a really good example for that case, because the game features 19th century firearms technology keeping pace with or even exceeding 21st century laser gun technology. That's just silly, but on a practical level, I would rather use a cowboy repeater than a laser rifle when I'm playing the game. You can probably complete Fallout without ever firing a firearm, so it's true that the game does not force you to follow a given development track. However, if you want to use big guns or energy weapons, these are not really available in the early game, barring exploitative player knowledge. There's not much progression within those individual categories, they're simply late game weapon skills.
