Video games invite us to a wonderful world of imagination. We can create and experience worlds so unlike our own, and maybe see things from reality in a way we'd never see otherwise. It's an infinite medium to explore ideas.

What can be some of the most fun in games, though, is creating something that would be much more difficult, or maybe even impossible, to create in reality. How many times have you looked at an airship in a game and wanted to fly in one? The thing is though, sometimes there's a reason these technologies only exist in games, and that's because they're just a little bit useless in real life.

7 Mass Effect - Omni-tool

One of Bioware's most beloved series, Mass Effect is packed with plenty of things to love. The detailed universe, the deep (and loveable) characters, and a rich variety of choices. Like any space-faring sci-fi, it presents plenty of renditions of the future that have been seen plenty of times already, though it has some unique pieces too.

For example, the Omni-Tool. Like the name implies, it's a Swiss Army Knife of sorts, packed with endless functions. But really, who needs a remote control mixed with a light sword? And is it really such a good idea to carry around an object like this that contains so much info on you? It's like you're begging to be robbed. At least you can protect yourself with it.

6 Final Fantasy 7 - Barret's Arm

There are plenty of adored settings across the Final Fantasy universe, from the sandy beaches of FF10, to the more traditional fantasy world of the original. That being said though, the series hit a peak with Final Fantasy 7, that Square Enix has strived to emulate ever since.

In a world styled heavily after the 1960's and ideas of what a future world would have looked like then, it's pretty spot-on in some regards. Massive corporate control, the poorest of society literally living in the shadows of the rich. Then there's Barret. An incredible character, and though his gatling gun arm is an essential part of his character, it's hard to say it would work in everyday life. You're not getting past airport security with that thing.

5 Assassin's Creed - Hidden Blade

It's hard at this point to actually define what Assassin's Creed is. On one hand, the original game is the purest of them in terms of systems, but is incredibly bare bones. On the flip side, its latest entries are full-on RPGs and sprawling open worlds — a far cry from the tenets of the original.

Yet the one thing (almost) all of them share is the hidden blade. It's one of those things that's defined the series, and become a massive symbol of gaming. The thing is though... how would it actually work? The games have flip-flopped on this, from it being spring-loaded to being pulled with a string. How does it even manage the force to puncture through someone's entire chest if it retracts so easily? To its credit though, it does blend in well.

4 Death Stranding - Cuff Links

Kojima's games have always been thoughtful in what they've depicted. The settings are studied meticulously, with anti-war messages displayed so prominently, and obviously, you would need to be actively ignoring them to miss it, and gamers sure do achieve that. That said, Kojima has just as much of a fascination with mechanical design, and has had plenty of tech of his own created with the help of Yoji Shinkawa.

In Death Stranding, there are plenty of pieces to help you along. Bikes, ladders, exoskeletons and transport droids, and all of them solar-powered. All of that would actually be great in reality. Where the turn really occurs is in the Cuff Links. Just as Fragile herself does, Kojima has handed you a metaphor, literally tying you to the world. They also siphon blood from your body — it's pretty hard to imagine a good use for that in reality that a regular ol' tube and needle doesn't already achieve. Unless you're in the market for metaphors, of course.

3 Batman - Bat Tools

Batman is one of the most iconic figures in basically all media. Beginning his origins in early DC comics, Batman is a major figure in every medium there is, and gaming is undeniably a major one. Getting to play the role of the Dark Knight is the dream of many, and Rocksteady games were some of the first to achieve it so well with their Arkham games.

Of course, this nit-pick isn't strictly linked to the games, but more Batman as a whole. As funny as it is to see a boomerang branded and shaped like a bat, it feels like maybe that shape and metallic weight isn't so conducive to flight. Of course, there's also his ice grenades, which just feel like an accident waiting to happen.

2 Deus Ex - Adam Jensen's Sunglasses

Built from the foundations of games like System Shock (of which Warren Spector was also the director) came Deus Ex, one of gaming's most well-known series. It has had plenty of bumps along the road, from constantly changing hands and games with very mixed reviews, but they've still solidified themselves as some of the best immersive sims and cyberpunk settings in gaming.

With Deus Ex: Human Revolution, Adam Jensen was bestowed upon us, a man turned into a cybernetics experiment after a brush with death. He never asked for it, but he was given this body packed with cutting edge tech all the same. Yet even with everything they put inside him, it's somehow the sunglasses that are the most unusual. They just slide into the side of his face. Can he control the opacity? Does all the HUD have to display when he uses them? Do they actually even work as sunglasses? It feels like a lot of work for what is essentially Google Glass you can't remove.

1 Dead Space - Isaac's Suit

It's hard to overstate how influential Resident Evil 4 was. Not only did it revitalise horror games as a whole, but it also reinvented survival horror, gun play and camera perspectives in gaming in a way that still stands to this day. One of the most immediate games heavily inspired by RE4 is Dead Space. Set within the confines of the USG Ishimura spaceship, the game has you exploring dark corridors while shooting the limbs off enemies to survive.

Dead Space, despite borrowing so heavily from RE4, introduced plenty of unique aspects itself, such as Isaac's suit. A smart way to remove UI elements while incorporating them as a light source and still being clearly readable, various meters are displayed on Isaac's back. When you think about this for more than a second, though, it breaks down logically. That design means everyone but you can see your vital signs. Humourously, the visor also gets smaller with each upgrade, undeniably making it even more difficult to see.
