For sheer boredom and nothing else, try Armorines: Project S.W.A.R.M. for N64. It's boring, the level design is a complete mess, the four weapons in the whole game are just variations on each other, the controls are terrible, the plot is derivative and apparently written by an eight-year-old, the graphics are chunky and lame, and the levels are all extremely repatitive. And what's sad about it is that the game itself isn't remarkably bad, it's just painfully, gut-wrenchingly boring.
