Yo, you wanna play MK4?
This was originally used as my review on Amazon.
A perfectly competent port of MK4. The default controls are absolutely atrocious, so you will need a controller pak available. I suggest putting your attacks on the C buttons, movement on the pad, run and block on L and R, and side steps on A and B. Without a controller pak, you'll be redoing these settings every time you play. For real, they are BAD. Block is on Z kinds of bad.
If you are expecting extra features or fancy bells and whistles, you'll be let down. This is very straight forward. You get one or two extra modes, but nothing special. You want to fight a lot of dudes on the same life bar? You can do that. You want to host a tournament at home? MK4 has you covered. You want to unlock content as you play? Get out of here with that nonsense. We've got punching dudes and we've got more punching dudes.
Also, the N64 port didn't have enough space on the cart for the FMV endings. As a result, all of them are redone in engine. This means the N64 version has the "best" endings.
