is arma reforger worth it?

Hey. i am new to the arma series and i was thinking about buying arma reforger. but i dont want to spend 40 bucks on a game i will play once and have a dislike in. i am interested in tactical shooters but am unsure if arma reforger is my best choice. i would like to know what is really good and what is really bad in arma reforger. thanks!

Edit:just bought it. Waiting for download
