I get your point, I hate that too. Games are branded as "realistic" when they aren´t, because they are not simulators, because game journalists might not have been in the armed forces of their country, or normal journalists just don´t know what the fuck "realistic first person shooter" actually means.
But sometimes, sometimes there is this ONE Developer, who takes a completely unrealistic but balancing aspect of shooters and MAKES it realistic.
Que Brothers in Arms, Hells Highway.
The older BIA games had nonregenerating health that, depending on dificulty, got replenished at checkpoints. THAT WAS IT...
The newest used regenerating health, but the very keen eye only noticed one thing. You never got hit, your screen just turned more reddish.
This was not to show that you just took a dozen Mauser rounds into your Chest and need to shrugg it off behind cover, no, this showed you of HOW CLOSE YOU ARE TO BEING HIT!
It was a "Danger meter" so to speak...it didn´t show you that you took damage, it showed you the POTENTIAL of taking damage, by having your ass be out of cover and fired upon, if it was red too long, one bullet found it´s mark and game over...
This effectively bipassed the "How can my character survive 100 bullets?" question, and implied "One bullet is all it takes" realism, but still being playable and balanced.
I like "realistic" playing experiences in my shooters, because, let´s face it, getting shot in real life is not fun, even if it does hit your SAPI, it still fucking hurts.
BOTH kinds of games have reasons to exists...MW2 style for people who wanna feel like Rambo and single handedly save the world by killing millions of enemies with their ultra low recoil .50 caliber sniperrifles and 7.62mm battlerifles, and then there are the people who want to crawl in the mud, take orders, take carefull aim because they have to account for gravity or even not fire at all if the situation does not actually call for a shot...
I like both, in healthy doses, but the people who screem "REALISM IS NOT FUN!" also think that realism means you die every fucking second from some stray bullet...you know, as if noone survived WW1 and 2...
Or take the guys who play racing or flying sims? You cannot get realistic enough for them, and one misbreak and you lose 5 positions you fought so hard for. "Where is the fun in that?" some ask...
Well, some people get fun out of a CHALLENGE by actually being able to negate all those realistic factors and still own the enemy...
You can also make a game realistic but still fun to play and balanced, by just hiding or covering the unrealistic aspects very good, as I´ve mentioned above, that made BIAs regenerating health system much more realistic then Modern Warfares, while effectively being the same.
