Posted this in the MK1 thread, but I guess it fits here, probably more so:
This game is so disappointing. I was hoping to relive some fun times from yesteryear but the lag, ridiculous difficulty, and glitchy achievements just break it. Everything was fine as I finished MK1 and 2 and got the achievements no problem, then I spent hours fighting Shao Kahn on MK3 only to finally beat him and get no achievement.
I started and eventually ended with the same character on all three games but it decides to glitch on me for MK3. I know it's based on the arcade versions meant for eating quarters but still, very easy should mean VERY EASY! The combination of the difficulty and the glitchy achivements is just terrible and the developers should be ashamed of themselves for releasing a port that apparently wasn't tested enough.
