Here are just a few reasons this could surpass Uncharted or Gravity Rush as the Vita's premiere action game:
1.) 2-Games-In-One: There are TWO entirely different ways to play this game. One way is a time-stop mode where time slows and you pick out your targets via the touchpad. This method of play is optional. The other way to play is more traditional button-based gameplay. You could essentially play the game twice in a row and have a COMPLETELY different experience. Or, you could mix it up during one playthrough, as yours truly will most likely do.
2.) Cool Character: She looks like a bad@$$ Disney princess. 'Nuff said.
3.) Everything PS3 Can Do, Vita Can Do...Just As Good: The Vita version of AC III uses the EXACT same engine as the PS3 version. That means the animations are the same and you can do all the same tricks.
4. ) Gorgeous Graphics: Every preview I've heard, they raved about how good this game looks. The designers ACTUALLY traveled to Louisiana to get a 1st hand look at the buildings they're recreating. That's going above and beyond the call
5.) Epic Adventure: Very little is known of how this quest will play out. But one scene that has been revealed is a sequence where you must steer a run-away horse drawn carriage that's on fire. Um...yes please. If they can squeeze in a few more sequences like that, to go along with the intense action, this could be one we'll remember for a LONG time.
