Player vs CPU

Is playing against the CPU even worth it? What difficulties, speeds ect. do you play at? What are the advantages and disadvantages does play against the CPU have? Im a beginning SF player, and Im wondering if my time spent on my console is actually going to do me any good when I try to make a name for myself at the local arcades.

Playing against the CPU can be good to learn priority on moves without spending years in training mode, and also is a good place to practice execution in a fight. The actual game flow is different in a game vs a live opponent, though.

5-6 stars seems like a good difficulty setting. Anything higher then that and the CPU will start DPing you out of 4 frame startup moves and such. Morrigan will do it anyways.
