Oops! This might actually be good for $20.
Oops! Prank Party is a goofy party game with a focus on pranking your friends. This is done by making the Mii-like avatars wear silly, degrading outfits. I've been dressed up as a banana and forced to wear a leotard. It's even more humiliating when the laugh track goes off and my avatar blushes.
Outside of the weird pranking focus, the game appears to be a pretty capable party game. The mini-games, totaling 100 in the final game, are fast-paced and fun, focusing on simple commands.
The demo I played had Master Mode and Practice Mode available. Both feature sets of five mini-games where you have to compete against three other friends or computer players. Master Mode seems to try to add a single-player component where you have to beat self-appointed game masters. They're fundamentally the exact same thing, though. There's also a Board Game Mode, but it was locked on the demo.
Oops! Prank Party has the makings of a solid party game that has a focus on being silly and quick. It's debuting for $19.99, which seems to be the perfect price for the kind of game that it is.
