They all reward teamwork, and to an extent creative play, though it depends on exactly what you mean by "creative". I don't think any of them reward roleplaying directly; even if it's desirable it's not really something that a game system can comprehend, only other people can, and the system is the thing that gives you the XP. Perhaps some smaller ones. Roleplaying is a reward in itself for many people anyway.
