Out of the dead fighting games that could be revived, Eternal Champions is not my first choice.
Still, I heard good things about the new Killer Instinct, though the original game wasn't as good as people make it out to be. If Sega does a good job at modernizing the gameplay and presentation, I would give it a chance. It's unlikely going to happen since Sega (the Japanese division at least) wants to stick with Virtua Fighter.
