I got into the beta as well and I must say its alot better than I had expected. I love the custimization, really upon till now I havent seen 2 chars look alike. Also the graphics and effects are really cool.
Leveling up is slow but that isnt bothering me because im never bored and there always citizens to rescue .
Another important thing is the fact that the city really looks alive with cars driving and alot of ppl walking on the streets.

IMO better than L2
