It took me about 20 hours to almost have 100% completion.
This is like an interactive episode that involves a lot of button-mashing and a dirty sense of humor. If you don't like South Park than don't play it. I would be surprised to hear if Kevin VanOrd was a fan of the show and that it wasn't effecting his judgement when writing this review, but then I have to remind myself that reviews are simply someones opinion.
There's a huge lineup of games I haven't played in my Steam library from the last sale, so it's probably a good time to cross a few of those off the list before I get back into console gaming when Titanfall comes around.
