I'm still playing it and became a real junky to it.
Social element is amazing, mechanics is deep and gives lot of tactical opportunities.
Experience is very non-repetitive and grind free. What I always thought open worlds should give but they never actually did anything similar to PR.
It's close to Planet Side 2, but free to play and fully non-commercial, thus everyone is equal except bug abusers and cheaters and server admins.
Shooter mechanics is designed to reduce rambo-ness and doing its job pretty well. And still it's 1 shoot 1 kill if you do it right.
Game is buggy, client and servers are crashing all the time, if you like aop, you will feel like at home!
Many things are not intuitive and controls/ui/graphics are shitty and not gonna become better (:
Sometimes no admins present on the server, so grief and teamkilling do amazingly devastating things.
There are shitheads present, which are waiting forward to insult or frustrate you or just do stupid things and ruin whole team hardwork on archiving the victory.
I doubt Squad will ever be anything similar due to the fact it's commercial project and should be much more fashion-like vanilla to get more $$$
I lead public infantry squads free for you to join.
