Well in terms of the games that I have bought for my 360 I would have to say that Prey was the worst one. They just made it a weak clone of Quake 4 with painfully repeating map designs and lame unimaginative storyline. the voice acting sucks and the gameplay sucks, They talked about how they would revolutionize thinsg with the portals and gravity effects..... but they are underused in the game with mabye 3 very small parts t of the game that actually have coolness and originality.

For the old Xbox I would have to say that Wrath Unleashed was the worst ever rip off of my money. It was advertised as a Strategy Type game along the lines of a war strategy game also with some fighting involved... I eagerly soaked up the reviews and Developer info and it was all misleading.
You get the game and start playing only to realize that is no real free form of playing with you having to strategise and fight an enemy... all the maps are pregenerated and you start with a set number of units "you only got like 4 different types and then only got like 1 or 2 of each in a battle... Overall I would call this game a LAME try at joining Chess and Mortal Combat that failed HORRIBLY
