Is this game with such freedom still a shooter?

Despite the many freedoms and the many missions the focus of the core still to kill enemy people. So far, the developers built more than 30 weapons, from knives to the grenade's all there..

Does Far Cry 2 follow the line structured gameplay of Far Cry?

No. Far Cry 2 is a fully accessible world. You will be able to explore a world of 50 square kilometer.

Devastation of FC2 vs. Crysis?

Although plants, trees, branches, buildings and other things are completely destructible, plants regenerate itself over time (as they grow in real life), and buildings get their actual form after certain time. Likewise soldiers will respawn at destroyed bases. As a result, the game is always interesting remain consistently different approaches in the game.

Will there be a map editor?

The answer is definitely "yes". However, it is still unclear how this works and what functionality it offers.

Does the weather as also as day-/night cycle have playful effects?

Yes. With rain around objects are burning significantly worse. The opponents sleep at night which allows surreptitious maneuver similar to Splinter Cell (not as pronounced).

The developers still need some time to make a final decision, but currently there is a ratio of 1:4 or 1:6 to reckon with ~ 14 hours a day and 10 hours in the night would be to play.

How long is the duration (may be false translated?) of Far Cry 2?

To expect more than 100 hours of fun if you explore the whole world and solve all the missions. With 50 hours to be a regular player and in 8 hours, if you just concentrate on the missions.
