ah yes, the oldest trick in all of FPS-History - just in a fancy 2.0 version... . i am 29 and play video games since 22 years ago - and due to various different forms of crosshair restrictions, screen-bumping effects or view-angle dis-centering in modern games, regardless of for 1st or 3rd person view shooting, brawling, stabbing, flying, driving - either directly meant to lessen/ disrupt aiming capabilities, or out of bad desing - i have a 3 X 2 millimetre triangle out of thin red plastic-bag skin attached to the center of my - only - TV (via simply wetting it in the first place) since 6 years ago, kiddoz! :) so yes, you "cheat" the game by something like this - but no, it is nothing evil or forbidden, in fact it's a funny little part of gaming history itself. feel free to feel more hardcore/ good/ bad*ss for not even using such practical tiny little helper-thingy's, or feel free to feel more hardcore/ smart/ bad*ss because of using them - but it won't change that it is neither a big, nor a hot topic - but instead just some of those topics that come up every now and then since practically decades, because some kid just learned about it for it's first time and starts a discussion out of it, gathering more kid's learning about it for the first time, vets that can feel awesome for knowing about it since ever like me - and guys that can feel awesome for very openly announcing how much of "unneeded" or "bad, bad, bad" the content of the topic appears to them. this thing repeats over and over again since soo long ago, it'za real classic of gaming - a very part of our modern culture.
