GTAIV fake box art...

I wouldn't normally post fan made box art but this one is pretty funny. It never ceases to amaze me how some of these things get passed off as legit for as long as they do (that is to say: at ALL).

Unless Elisha Cuthbert, Vin Diesel, and Michael Madsen(?) are not only doing voices for GTAIV but actually lending their likenesses to it(I must've missed that press release!), then you've gotta believe it's a fake.

Crackdown vs. Riot Act

The localization process for a game sometimes brings about more than just a change in cover art for a game and this is evident in Crackdown's localization for Japan, although being renamed Riot Act sounds more like a trademark issue than a localization issue.

The anime style art on the Riot Act cover is definitely an attempt to make the game more appealing to a Japanese audience even though the in-game graphic style is better reflected on the Crackdown cover.

I can't say I'm overly fond of either cover and there's definitely not a clear winner in this case. The anime characters of Riot Act seem to have more personality but the main guy is just so goofy looking it brings the whole thing down. The US cover is way too inspired by the Grand Theft Auto covers for it's own good but I'm sure that's intentional. The game itself is inspired by GTA so they might as well ape it's box art too.
