in 2001 my parents bought me my first PC that was mine and mine alone. With that PC came Lemmings Revolution.
Perhaps my favourite part of the game, is when you reach a level you cannot solve, you are not required to finish that specific level, you can sidestep it to reach the final level. This fact alone makes it an outstanding puzzle game, and being such an old game, little exists of walthroughs and solutions on the net. This truly is the ultimate puzzle game, not too hard but not too easy. So next time you're at you're at a Garage sale and see a copy, be willing to fork out the $5 price tag for several hours of enjoyment.
Its no zelda, but I love it!
