Not sure how scoring the bug-filled WWE '13 as a better game than WWE 2K14 is justified. '13 received an 8.0 from this website, notwithstanding there were features of that game that flat-out did not work as advertised (looking at you, Universe mode and Community Creations servers). In addition, there was notorious two-count bug which removed all drama from user-vs-AI or AI-vs-AI matches; with drama being arguably the most important component of professional wrestling, these two things in tandem absolutely ruined last year's game for me, notwithstanding how great Attitude Era mode was (and I agree that AE tops 30 Years of Wrestlemania mode on account of cohesiveness of the package).
If there's anything at all about this game to like, it's far more polished than any Yuke's wrestling game to-date, and that alone makes it much better than last year's game for me.
Ultimately this is just a difference of opinion between the reviewer and I, however. I'm enjoying the game, that's all that really matters for me.
