I'm sorry but this logic just does not make sense. Like at all. Why exactly would a character being playable in a home port be any less significant than the same character being playable in the arcade version? Last time I checked they're still the same game, just on different platforms.Uh, home ports of MK games that were originally released in the arcade do NOT count. Everyone knows this.
The ports were handled by a different company than Midway, but are you seriously going to tell the people who grew up playing with Rain on the console ports of UMK3 that Rain isn't an MK character because of that?
