I hate how pretty much all the bosses in games like Sonic, Mario, and Zelda take 3-5 repetitions of the same process to be defeated.
Pick up a bomb flower, throw it at the inhaling fire-breathing dinosaur, wait for the bomb to explode inside him, hold the shield button as the dinosaur rolls around the arena once and stops right in front of you, and repeat, and repeat again.
Why can't it be more interesting?
