I've finished it just now. The city is giant and open. The way to do missions is your choice, almost without limits. I've missed few things, because RTS style games are not my choice, but it's not a handicap. RPG elements are enough to got the feeling without loosing in stadistics. The history is too classic for the genre, nothing about a heavy trama. And no bugs to me, except in the final level, where the enemies has trespassed a few walls a couple of times. Well, I could point a few minor negative things, but nothing serious, and the general taste of the game has been really fun and envolving to me. I'm pretty sure this game will be a gem in the next 10 years or less. Enjoy.
