i got the subzero premium edition for 60$ at walmart. it comes with a perfect arcade port of MK 1 , which is pretty cool. also comes with some little tin card with subzeros stats on it. basicly if you want MK1 its 10$ more, i thought it would be cool to have.
i used soul cal as a example because of the 3d fighting system. it doesnt flow like SC does because SC is more of a fast paced game MK:D seems to be more toward technical fighting and quick 5-8 hit combos. the online play is what does it for me, its just so cool hooking up with people online for some matches. has online ranking and everything, also can do puzzle/chess mode online.
