Let's be real here. No one wants to play a video game that is 100% realistic.
The whole point of playing video games is generally to experience a different reality and escape from our day to day lives. But when you look at some of the common behaviors and cliches in video games in perspective, they can be pretty comical when contrasted against the real world.
Here are 10 of those things!
What RPG or adventure game would be complete without the ability to invade people's homes uninvited? And the thing that makes this even stranger when put into perspective is that, rarely, the people inside seem the slightest bit put off by this behavior. Try walking into someone's home in real life and you will most likely be in for a bad time.
Games like Skyrim have started to add a little more nuance to this particular cliche by forcing you to be a bit more secretive about your kleptomania, but it is still a common antisocial behavior in many games. Once you've barged into someone's home (see #1) you proceed to dig through their treasure chests, drawers and closets to take the contents inside. And once again, the original owners of these items rarely seem bothered by your grabbiness. In the real world, this is called theft and usually ends in legal action.
I understand the need for health items in games, but can you imagine doing this in the real world? You've just been shot, and you come across a turkey leg laying in the middle of the street. You pick it up, gobble it down and, tada! Everything is okay. In real life, this is just about the quickest route to food poisoning, and you will still probably bleed out.
This one takes several different forms, and they are all equally bizarre. Look at a game like GTA where you can have an army of police chasing after you, but as long as you stay out of view long enough they just give up. Be pretty nice if this was truly the case. Or what about all those stealth games where hiding behind a box for awhile makes your enemies seemingly forget you were ever there? And finally, that first-person shooter cliche where you can get shot a couple times and as long as you don't get shot again, your health will eventually regenerate. Be nice if any of these scenarios played out in real life, but we're just not that lucky.
I'm not trying to say video games are sexist, but sometimes, video games are a little sexist. This cliche most often applies to female characters and assumes that a female warrior, soldier or even just a random NPC would choose to show as much boob, butt and skin as possible instead of choosing a useful outfit for the particular situation. About to go into battle with a dragon? Put on a tiny bustier and a mini skirt. That'll help you fight. Until your nipples pop out.
Okay, I know this one is a little stupid, because no one wants to play a video game where you have to take bathroom breaks (unless you play the Sims which is an exception here). But when you think about it, it is pretty weird that you can spend 100 hours playing a video game and the character NEVER goes to the bathroom. YOU have to get up and go, but the characters in the game never do.
I understand a piece of armor giving you a little more defense, or maybe a certain weapon doing more damage based on the general logistics of what it is, but why would a sword give you more intelligence? Or more life? I wish I could buy a hat in the real world that would make me more smarter. Someday.
I recently played Undertale, and that game actually had a sort of running joke about this one. The option to sell was always there, but nearly every merchant in the game would refuse to buy your old crap which is far more realistic than most games. Though it's very convenient to be able to offload unneeded items in exchange for cash, in the real world, very few stores are going to BUY stuff from its customers.
Some games try to deal with this a little more realistically. Again, Bethesda games like Skyrim and Fallout have weight based inventories that eventually fill up, and one of the best systems I've seen is in the last of us where you have a VERY limited inventory, and every weapon you have is actually visible on your player, adding a high level of realism to the inventory system. Most games however do not handle inventory very realistically however, allowing huge numbers of weapons to be carried around, or capping things like health potions at 20, 50, 99 or more. I'd be hard-pressed to carry 99 pennies on my person at any given time, let alone 99 bottles of liquid.
I guess I can't prove that the real world doesn't work this way, but most of mainstream science points to no. In the majority of video games, if you die, you pretty much pick up where you left off, or at worst, at a point not too long before your death. And with that said, in regards to this particular cliche, most NES games are actually more realistic as, though you usually get to die a handful of times, eventually, you're done. You're dead.
