I had a couple ideas for different Kombat modes for mk6. There would, of course, be regular arcade and versus modes like in MKDA, plus Konquest, but Practice mode would be more like in MK4 where the opponent can be either inative, active, or human, with infinite life for each character.
Also, there would be a "story/war" mode, where you choose the allignment of your side: good, evil, or neutral(each side would have the same number of characters in the game). If the player chooses good, he'll fight random evil characters with random good characters; vice versa if he picks evil; and if neutral, he'll fight more or less anyone who stands in the way of the characters' goals. Also, there would be little FMV movies showing how each fight starts, what happens afterwards, etc. Many fights would be between characters who want revenge on each other, and in the last one you choose your character to fight the Dragon King if good, Raiden if evil, or...well, it depends if neutral.

Tell me what you think of these ideas.
