Those are very minor tweaks, and additions. Nothing substantially improved or drastically changed. They made a big deal about being a big daddy, but it's essentially no different from playing Jack. Delta is a very weak model big daddy, and it doesn't take much to bring him down. It's not like you're really noticeably slower to begin with either; not to mention you get that fleet foot perk right off the bat anyhow. Also the under water sections were another thing they had touted, but really there was only short instances of point A to point B. If 2K wants to keep milking it as a franchise then they're going to need to do something besides stand in the original game's shadow.
