Completed Batman: AA. Good game with well integrated action and stealth elements. Storywise however, it typically suffers from any games based on an existing franchise characters: No one in the game has any sort of character development at all.
Thus the plot pretty much is the cliche of Batman kicking Joker's arse and happy end.
Now I'm playing Resident Evil 5. Single player is down right awful due to horrendous AI. Its impossible to play at all. However its a blast to play it for the multiplayer, which unfortunately, good gaming partners are so rare to find online by chance.
