Mortal Kombat Gold is probably (IMO) the best Mortal Kombat around, other than Deception (i cant comment on this as we here in England don't get it until next week ). The graphics on the dreamcast version are supperb, and it runs beautifully if your T.V. supports 60Hz.
MK1 only had 7 playable characters with 7 Fatalities total. In MK Gold you get 6 EXTRA with 12 EXTRA Fatalities and 4 new stages. This is on top of all the characters from MK4, and all the stages.
Also lets not forget that MK4 had the best endings out of any of the games, and they look even better on the Dreamcast.
P.S. Sektors ending on MK Gold is the best of all time :twisted:
