I really enjoyed Gravity Rush, and so far am really enjoying Liberation.
Could AC:L be better technically? Absolutely. The "fit and finish" is clearly sub-par. But so far, I have not encountered any game breaking bugs, and am having a ton of fun.
We have a super-expansive open world thatits pretty impressive technically (excluding bugs) that we can play on the go. The combat and free running, what I like most about these games, seems to live up to the console versions I've played (AC 1 and 2; in fact, this surpasses 1 in my mind). The plot is sparse, but I never really thought the beat by beat plot in any AC game was very clear or interesting. The characterization of the hero is, I think, very good, especially compared to Altair. And I actually appreciate the notoriety system. It never made sense to me that I could run my ass around Italy in a silly hooded costume, climbing walls, and the majority of the populace would simply ignore me. Having to deal with the consequences of my actions in this way makes sense.
I am very excited.
