Growing up playing these kinda games, you kinda just normalize it. I came out normal.
Started with Duke Nukem 3D, Doom, Quake and Mortal Kombat 2/3.
I think I'm a bit more messed up than I would be without it, but nothing too serious.
I grew up with these games, too, but if you have internally normalized that which is inherently abnormal, it may manifest in subtle ways.
