A few exclamation marks, phrases like "a heap of single player content" and just general construction makes it seem like it's made to promote the game. Is it just me? And if not, what are the rules concerning pages that can be deemed "more subjective than objective"?
Yup, that wiki sucks. But I reckon AjayRaz knows the score, so when that information was added, a press release was probably all there was available. No edit dates, so can't tell.
The game's out now, so you are welcome to go play it and rewrite the wiki to resemble what you feel is a better style. I reckon you know the score also! Worst that'll happen is somebody else comes along and puts in twice the effort to expand it again. :)
