Yes. "Realistic FPS" games have 3-shot kills, regenerating health, and the ability to carry TWO guns. If I went up against more than 1 guy at a time, I would fucking die.
I grew up with Doom. I had 100 health, and could pick up potions that INCREASED that amount and armor that decreased the damage. I carried 9 weapons and had the option to kill EVERYTHING in the room with the BFG if I so chose. Oh! And I could take on 50 guys AND WIN.
Frankly, I like unrealistic games. Gex, Enter the Gecko? How realistic is that? Not. How much fun is it? A TON.
