I really like how B/W added ending animations on some of their game modes.
"Punish the Guilty" shoot concrete block off Tam's feet.
"Farley Claymore" throw Farley thru window.
"Duel of Wills" grab / control the phurba.
"Survive the rope bridge" Cut the bridge / guys fall.
"Tank Chase" Tank goes off cliff.
Wish more games did this. I prefer less modes, but fully complete like these are. Both these games get my vote.
