I don't know quite how they pulled it off, but they managed to ruin bejeweled.
Bejeweled was a beautifully simple game:
Swap two gems to make at least 3 in a row. Those gems disappear and the gems above drop down to fill their spot. More gems come onto the board from the top as needed.
Three frickin' sentences to describe the game. You'd be hard pressed to make a game that simple to explain, except maybe something like Click the Yellow Rhombus, where the title of the game serves as the instructions.
But Bejeweled 2 has to give you nifty, shiny graphical effects that make you feel like you are going warp speed, a scary HAL-9000 voice for certain events, and special power up gems for 4 and 5 in a row.
Is nothing sacred anymore?
