While WWE 2K14's "30 Years of WrestleMania" was a fun little time-killer, the fact that it was presented as the game's defacto single player campaign was simply laughable. As a mode on it's own, it's fine, but it lacks the depth of a true single-player experience that WWE 2K15 really needs. The single-player mode in most WWE games have been pretty ho-hum, rarely ever feeling like an appropriate venture for the solo crowd. While it's utterly impossible to create a separate story mode for each individual WWE Superstar, that sense of having a beginning, middle and end would probably do the series some good. The concept of telling a single story over the period of a year, while giving the player an almost Mass Effect-esque control over good/evil alignment is endlessly tantalizing; which means we won't get it.
