My personal pet peeve is how gameplay can go out the window when pretty graphocs are involved.
With the Master System you had 2 buttons and a D-pad. There were very few true FPS on the MS, but if there were, the buttons would be shoot and chamge weapons. Now a typical conversation is:
"Wow. This IS a good game. How do I shoot again?
"You hit the second shoulder button to take the safety off, then you hit X to lock on, then A and B together..."
Too complex. Why can't it be simple?
