If you like Arma 2, you will probably like Arma 3 too.
Graphics are great (if you have PC good enough).

Gameplay is as it should be for Arma - tactical. I think this is the one of the most realistic war games out there.

There is also a preety nice community - you can play community created King of the hill, Wasteland, other missions.
Don't forget to grab a microphone because working with team is so much fun and is actually what this game is about - tactical teamplay.

In short: If you like war simulators with great graphics, teamplay and nice community I would recommend you this game.
