I have to admit having a real love / hate relationship with Lemmings.
Yes, it’s original, and yes, it’s addictive, and yes it’s pioneer blah-di-bloody-blah. It’s also super frustrating, requires way too much pixel-perfect precision and the level designs were torturous beyond belief. Even back in the day it was known for being rock hard, and that was before the industry wide wussification that has infected every game made since 1997.
But hey, fun fact: the game was originally prototyped on the Commodore 64 before being initially released on the Amiga. And then the official C64 version didn’t come out for another five or so years. It’s still my favourite.
