Arma 3 or GtaV

I'm a hard core GTAV-er. It's a great game especially if you can buy all of the stuff. Lots of cool stuff you can do.

Arma 3 I have as well, played it once which proved to be quite complex and the people I played with were immediately telling me to do stuff like I should already know what all the military speak means? Wouldn't recommend it but I might try play it again.
