Because It isn't truely arcade perfect.

because mk trilogy is just a fake game, and mk3 is the real thing. mk3 mat2 is as close to the arcade version as possible.

Because MAT2 MK3 is the arcade version. So, the characters are the size they were in the arcade, which was larger then MKT because N64 couldn't store that size and PSX couldn't display that size (without choppiness).

Loading times are different because MK3 for the arcade was designed to run off of roms where accessing was extremely fast and are run on an emulation of the original hardware that uses 32 megs of ram.

MKT for PSX was designed to run off of a slow loading CD and only has 2 megs of ram.

I don't know the difference in sounds between MAT2 MK3 and the actual arcades, but the PSX version had CD track musics that sounded great.

And MKT is as 'real' of a game as MK3 was. Probably more so since its gameplay was deeper and it had more characters (talking about the PSX version at least).

i know MKT is not perfect i know it has long loadings and slows and MAT2 Is alot better than MKT But MKT Rules it has so many characters Brutalitys,Animality,mk3,2 in MAT2 Is kinda cOOL.I hate Anti-MKFans
