Due to Windows 8 I'm switching to Linux. I still use Windows for Steam, but it won't be on my next PC.

I agree. Knives, choke-holds, rifle buts etc... Should be done more realistically than COD. But it would be nice to be able to sneak up behind someone and knife them if you're low on ammo, or you just want to be covert.

It'd be interesting if blood attracted sharks. It'd give you something to think about if you were injured, especially if you were low on ammo. It might take some time for them to show up, and they may not show up at all. But the chance of a shark appearing after an altercation would add some anxiety to the diving missions.

Seeing some wild life also adds to the games realism. I liked running across the snake in the infantry demo.

Apparently Greece doesn't have sharks. It is set in the future though. Maybe the conservationists will introduce some sharks to Greece by then. Probably best left for the mods though.

Motion blur is just a nuisance to me.

My wife and I purchased Arma 3 so we could play together. It's odd seeing her character as a man. We would both prefer to have her character as a woman. There are female soldiers in real life. It's not like this is an odd request that would make the game less realistic.If this was a WWII sim I'd understand, but it's the 21'st century. If we have to mod it we will. But she's a paying customer, she shouldn't be treated like a second class citizen.
