Coot,
The game interface (GUI) is easy to navigate and use. Maybe a little more simple than RoF one.
Graphic configuration is simple, just choose between three pre-set modes.
Sound too, just select you hardware - headphone or speakers.
And set in game volume at 100% and reduce for comfortable level in Windows mix,
or you lost some sounds, like hits in your plane.
But controls, specially if you choose use CEM (complex engine management) is a bit confuse to understand - translation/names used - and to set, some commands are interdependent.
But since is based in RoF, don't cause more problem for users of this game.
To get the game go to game site, create a account (advisable create a new exclusive email for use in this account - make easy sold the key later if are the case) and buy the game (or buy from Steam, if you are Steam user).
You will receive the key via email, then log in your account on game site and register the key.
After download a client that will download the necessary files and install the game automatically.
Done, open the game insert your account email an password, save.
After this, if you are connected in Internet you have option to play in Multiplayer servers or play the SP Campaign (for get the famous Unlocks).
Or if you are ofline you have option to play Single Missions (actually ~15) and use the Quick Mission Builder (QMB) that generates short quick action missions.
