Got some time in game and here are my thoughts so far.

Pros:

1)Teamwork seems to have more mature players.

2)Graphics are nice.

3)I find it challenging.

4)Lots of options on entry and defense.

5)No way to turn off friendly fire.

Cons:

1)Server issues

2)Kit is limited

3)Limited amount of operators.

I like the game so far.Though it does need some work.
My main gripe is the ability to swap kit between operators you unlock.Half the SAS guys all use shotguns?
I like the unique ability some operators have.You have two classes attackers and defenders.
Depending on what team you are dictates what class you play as.

I mostly play terrorist hunt with other players.Server issues are bad and I have been cut off mid-game.Which is very frustrating.
For single player there is Situations.Basically challenging tutorials.
I found the AI not bad.On realistic I have yet to finish a situation or terrorist hunt.My gripe is the AI will yell out and give their positions away etc.

IMO,the best way to play this game is with folks you know.I played a few rounds with a team that planned and communicated and we kicked butt.Then I played with Jackasses that went COD.And we lost.

I do like playing as defender as you can put out traps,tangle foot wire and reinforce walls.

I love that you can't turn off friendly fire.Some other players found that out the hard way.As did I with a breach charge when I killed my team. :D

I will post more as I play.

I just bought this. Playing through the 'Situations' now, then I will likely try some matchmaking (or whatever they call it). I can't wait, this is definitely fun so far! I bought the game through Uplay rather than Steam, and I have no idea how to link it so it shows that I'm playing it to my Steam friends. But I'll try to get into the teamspeak whenever I'm playing online games so you guys know.

Who else has the game? I'd love to get some groups going!

The Patch is out with a new map and Operators.There is some improvement and it is easier to connect etc.
