Should I get Squad?

The steam summer sales are coming soon and I consider buying squad as it will be ~20€ (40 is too much for me :P) I've never played any military sim game but I have seen many videos and it seemed to be a very cool game. Especially now that there is far more content than there was originally. I prefer this game to Arma as it seems to be more "casual". Arma seems so slow and the operations there last hours and generally Squad seems friendlier.

Should I get it? I mean there is the steam refund but i am not really sure... By the way, since im 15, is squad a suitable game? Im not asking bc of the violence and stuff (who cares you find younger kids all over fps games) im just asking if its gonna be fun enough. you know..

Also my laptop can run several games (on low mostly) but will it run squad? www.systemrequirementslab.com said that I can run it at minimum settings.

my specs: CPU: Intel Core i7-4700MQ @ 2.40GHz RAM: 8GB Graphics: Nvidia GT740M + some intergrated intel graphics OS: windows 10 64bit

Thanks!
