The reason I believe there is a jump button instead of a climb button is probably because it is much easier to do. With jump you just do an animation and move the player in whatever direction.
To climb you need to detect if an object is there and that you can climb on it.
I would prefer climb myself.
As to crosshairs. When you say future do you mean new militart FPS or future as miltary FPS set in the future. If it is the former then I agree. If the later I wouldn;t mind it so much since some sort of futuristic targeting could be done. Hopfully much better than it is done in games.
