Heard of evolution?
You're right, god forbid I could think that after mor than 100 years, they could be different.
I'm assuming that, like the Skaarj, there are many different "breeds" of Krall. Also, lizards and such evolve at a much faster rate than other species, add some sci-fi-ness and maybe some Necris tinkering, and why couldn't they look and act like they do currently?
What you're arguing is purely semantics. You don't like the Krall's design not because they don't look like the Krall from Unreal 1 but because you don't like the design, either that or you simply refuse to believe there is ANY possible explanation, when plenty of possible explanations are there. They simply don't look that different from Unreal 1 Krall.
This makes no sense.
Considering the amount of content in UT3 that is based on previous Unreal games, I hardly think the one single change you are talking about will have any effect on the universe.
Sorry, but this again just reiterates to me your lack of understanding of the Unreal universe all around.
The gameplay doesn't have anything to do with the Krall model. That's completely silly.
Additionally, the "consistency" in this game, in terms of what you are talking about, has nothing to do with why people don't play it. Nobody is coming on here starting threads like "I stopped playing UT3 because the Krall look different than I thought they would coming from Unreal." They are making threads like "Go back to UT200x movement/gameplay" (which nobody but UT200x spazboys want) or "why does Gamespy suck so bad" or "who decided to have virtually no avril ammo around".
Sorry, you're just not making a point that I can agree with.
