Im enjoying this so far, the fact that there are so many worthwhile enjoyables makes the single player modes much more fun. RTW is the best story mode ever IMO, and being the length it is, is totally excusable for the quality of the storylines/cutscenes.
I've completed the RTWM as HHH, Punk and Mysterio so far, and Im pleased with what I've managed to unlock;
Spoiler: Click here to viewHHH (DX entrance, DX attires, Jillian Hall) CM Punk (Locker-room area, Layla, Tazz FTW, Punk's alt. attire) Rey Mysterio (Mysterio's alt. attire, Hawkins & Ryder, SNME arena, Mr McMahon) Probably something else I'm missing on one of them too.
