Anyone else notice this?

By the end of Final Fantasy 8, Squall opened up more and was seen actually smiling.

In games like Dissidia he's consistently dark and brooding.

Now, this may not be the best example. After all, they may be trying to capture the character as they are generally known or the spin-offs may not be taking place after the completion of the game.

My hope is that you get what I'm generally talking about. So discuss this. Perhaps you can think of some other examples where characters personalities reset to their disc 1 selves?
