10 Most Ridiculous Things Gamers Can't Stop Arguing About
7. Screen Looking

For the uninitiated (said in Tom Hardy's Bane voice), the concept of Screen Looking relates primarily to couch co-op multiplayer sessions of (tragically) days gone by, and is most prevalent in first person shooters like Goldeneye 007 and TimeSplitters.
A heinous and morally reprehensible rival would literally look at your section of the screen to figure out your location and ultimately your game plan, and would adapt their strategies accordingly - basically cheating, then.
But is it really cheating? Surely it's just part of the game. How else would your older brother figure out you were hiding in a bush (camper!!!) if he didn't look at your screen to work it out? It's just solid strategy at the end of the day.
In a bid to negate the impact of this questionable tactic, the internet is awash with all manner of weird and wonderful workarounds - usually cobbled together out of cardboard and hope - which help players to prevent their sneaky siblings from committing the dastardly deed.
As a slight aside, Screen Looking has a sibling of its own: Controller Looking (Pad Peeking?) which can most commonly be witnessed in the wild during penalty shootouts in FIFA and Pro Evolution Soccer.
