It is more fullfilling, indeed, but for reasons like complex and close interactions with other players, graphic fidelity of a terrain, etc. The advanced flight model in Arma isn't that bad. Rotor Dynamics libraries are of military-grade, but those implemented in Arma lacks crucial modules, a real shame. However, both RTD and a damage model are modable to a great extent.
The same here, really. I guess, we are old schoolers, aren't we?
