Here's what the newest OXM magazine says about these BK games:
Big Bumpin' (5.0 score, not bad for $4)
They start by saying that you at least get your $4 worth. The controls are limited to a thumbstick and one button (for turbo), which means anyone can control it easily. Games can last anywhere from a few seconds to a few minutes... there are even a few unlockables to get after winning tourneys.
At the end of the review, they say that (obviously) the 360 version looks better than the Xbox version... the 360 version also allows online play.
"Hands down, it's the best sandwich themed bumper-car game ever."
Sneak King (6.0 score, not bad for $4)
This game lets you be "The King", and the object is to sneak up behind people and surprise/scare them with deliveries of fatty fast food.
"Moments like leaping out of a leaf pile to bestow chicken fries with a royal bow are just too entertaining to miss. As a surreal novelty item, SK is worth the money. As for the sandwich you'll have to buy with it... hey, we just review the games."
PocketBike Racer (6.5 score, not bad for $4)
"It actually has lots of environmental detail for such a cheap game."
"Powerful turbo boosts let the King himself catch some big air."
"The stop and go action, the occasional jumps, and the sheer ridiculousness of what you're taking part in lends every race a manic aspect that elicits more giggles than groans. And come on, what other game can give you a quick multiplayer fix for $4?"
