Well I can tell you for one, aiming your firearm down the sites on battlefield seems like a better "simulator" than dayz arma etc. From my past experience shooting REAL weapons as a hobby such as AR-15, SKS and assorted pistol platforms it seems ridiculously easier than dayz which doesn't make sense and it's just a pain really.. Acceleration in the windows mouse setting is also disabled for me, I talked to several friends about this and the mouse coding definitely needs a fix. I'm sure they'll fix this it's only in alpha, I just hope they read this! Keep in mind I'm talking about aiming down sites AND controlling the characters left/right to guide it, the feel is just a mess.
