Depends on what mood i'm in and/or who I'm playing. There are things that I hate and like about both games. MK1 has more balance between all characters, more counter moves, more offensive gamplay overall, Sonja is the only chracter that can't be fought offensively, cause she can't be pressure jabbed. She is also only one that has an infinity, and only broken character. MK2 has more characters, random select, more headgames, more moves, which adds to overall more variety, and a faster gameplay feel. I also think MK1 requires faster or better timing/quicker relflexis than MK2, at least that's what i observed from playing soultaker, even though MK2 is a tad faster. Either way, both games are pretty different from each other, which kinda messes me up when I use MK2 strategy in MK1 that doesn't work, but i use as a reflex, and vice versa.
