It'd be great to get some more fleshed out missions with old characters from previous titles. It was great to see Sam Fisher again but his mission was less of a fun challenge and more of a "make me want to jump off a bridge" level of BS. In future a mission with say, Hunter Team (from GR:FS), should have more options of approach. Stealth, especially in this game where the stealth mechanics are mediocre at best, should be optional and missions should have the ability to transfer into an open gunfight without a mission failure.
