Give Mortal Kombat Trilogy Thunder Edition 5.1 a shot. What is it? It is a FREE fan made remake of MKT in Mugen with suprisingly good quality. It features every single version of every single character in MKT. So for example the MK1, MK2 and MK3 version of Scorpion is featured in the game. It takes a lot of liberties with adding more super moves, combos, fatalities etc. It is its own thing but well done IMO.
