Found my original Gameboy at the weekend with a box of games, most pretty good, but the one that I sat down and played and that kept my attention for an evening was an objectively terrible game - Mortal Kombat. Even by the limited standards of the Gameboy, it's a terrible port. 6 maybe 7 FPS, gutted characters and move sets, animation frames in the single digits, it's a terrible game but I still can't help myself from liking it.
I remember getting in with the Gameboy and a strategy guide and pouring hours and hours into it and somehow managing to convince myself that it's a was a semi-decent game. Not knowing any better really I memorized all the moves, the fatalities and the timing needed to beat the thing and that stuck with me. I can still complete this awful, awful game on one credit and spent most of Sunday doing that. It's a terrible game, but I can't help liking it.
