Remember Marble Madness? You may have subconsciously blocked out the painful memories the frustratingly difficult and finicky game can bring. Unless, of course, you beat it. In which case your life has already peaked -- that was probably the greatest achievement you'll ever experience, so it's all downhill from here.
If you'd like to spend your remaining years enduring similar ball-rolling-based sadism, you're in luck. Crescent Studios has brought us Gears, a game about rolling a sphere through ludicrous concoctions of gears, pipes, ramps, moving platforms, and such.
