It's occasionally very entertaining...but only occasionally. In the end it comes off as too uneven; any time Gametap started enjoying themself too much, the game would smack them down with another boring mission or irritating control issue. And so, it's hard to recommend it for anything more than a rental...and only if you like your games campy, offbeat, and lewd.
Pros: Occasional laugh-out-loud moments; Big Willy's destructive rampages; surreal and unpredictable mission setups.
Cons: Uneven and unreliable controls; some missions are boring, even irritating; the wang jokes get really old.
