That's the problem with a lot of games. They place a super-weapon that is far more superior to everything else, that dominates the game-play. I've never liked those though, it takes an element of the fun away. I would only like stronger weapons, if you get to use them at certain points only or for a duration of time. I guess it depends entirely on what the weapon and its power is. In some games, having a certain weapon or strength can make it too easy. But then in some other games, having that better weapon or ability helps a deal, and doesn't make it feel too easy to play.
I hope this one will achieve more than the previous games in terms of combat, with a lot of different options. And I like the sound of having to mix it up. Sounds more challenging. Should be a fun game ^_^
