I liked Mortal Kombat. I liked Mortal Kombat 2. I liked Mortal Kombat 3 a little less. I didn't like any game after that. MK 2011 was supposed to be a recognition that there are many people out there like me--people who want them to remove all of the content, get back to basics, and make those basics enjoyable and well presented. Or at least that's how I read it.
Without getting in to which specific characters I like or don't like, in general, announcements about how "tons of old stuff is back" concern me. I'd be happier if they announced 10 characters that weren't in the game as a way of proving the point that they're moving away from character roster and bought-into-their-own-bullshit canon garbage.
