I only played Splinter Cell through a PC demo and I get pissed off when I'm 90% done with a mission and just because of one thing I have to start all over. That is also the case with R6 games.
As for GRAW, my only chance of playing it was with my friend on his 360. Right when we spawned, I saw red streaks on my screen, so I thought I was getting shot. Then I see a lot of tangos and boy did they own us. I wish I could see my gun on the screen, so it's easier for me to know when I fire.
The problem is R6, as much as it tries to be is not realistic. Maybe it has to do with the AI, but also with the HUD. It might be harder, but they need to remove things like health numbers, ammo gauges, menus and of course, CROSSHAIRS! How do you aim without crosshairs? Well, how do you think it's done in real life? IRONSIGHTS!

And that's realism^
The funny part?
The picture is from a mod on half-life called Hostile Intent. When a mod that is FREE is more realistic than a franchise that supposedly is supposed to be a simulator, it's clear those games were just made for the money. Red Storm needs to actually fire a gun and see if you have floating crosshairs in real life.
