The line between fact and fiction is a thin one, and people have a nasty habit of breaking it. Take the somewhat disturbing enthusiasm of certain Avatar fans.

With a video game, thanks to the medium's unique immersive capabilities, the lure of fantasyland is particularly strong. Doree, for instance, has been known to sit rigid on the sofa after intense bouts of Halo, tapping bemusedly at imaginary buttons as he tries to remember how to walk without a controller.

Consider also the following futile but highly amusing efforts to bring classic games to life. In some cases, the actors have managed to retain a sense of humour about it. In others, well - best just watch.

We've scored each game and its real-life "port" separately. Thanks to Patrick Runte for the article shot.

1. Tetris



Game score: 10/10
Life without Tetris? Unimaginable. This isn't just a game, it's part of our genetic code.
Real life port: 6/10
It's not Tetris's fault - people are to blame. We're just too rounded and asymmetrical, with the honorable exception of Victoria Beckham.

2. Assassin's Creed



Game score: 8/10
The Crusades weren't the West's finest hour, so killing Templars in the persona of an Arabian assassin can only be a good thing.
Real life port: 5/10
There's nothing more embarrassing than a geek doing parkour, unless it's a geek dressed like a member of the Ku Klux Klan.

3. Pong



Game score: 5/10
Pong is like our very first teenage love affair - we're glad it happened, but we certainly wouldn't care to relive the experience.
Real life port: 7/10
Sheep are a bunch of retroheads, evidently, but only being able to play at night/with Welsh farmers is a bummer.

4. Mortal Kombat



Game score: 8/10
One of gaming's original bad boys, as detailed in our controversy round-up. We like a rogue, especially wearing pyjamas.
Real life port: 7/10
None too shoddy in reality. Loses points for use of a green screen, and for crass ending joke. Raiden must be spinning in his grave.

5. Call of Duty



Game score: 9/10
First-person shooting perfection. The multiplayer mode is a more than serviceable substitute for a girlfriend, providing you like it rough.
Real life port: 2/10
Ewww, we don't want to actually see the shrill testosterone-addled juvenile militants we play against. Nice simulated teabagging though.

6. Mario Kart



Game score: 9/10
Not so much a kick up the bum for the racing genre as a tortoise shell to the face.
Real life port: 8/10
Runs a heck of a lot slower, but startlingly enjoyable. As throwing ninja turtle action figures at people often is.

7. Parappa the Rappa



Game score: 8/10
The first "big" console music game. Could still take 50 Cent to the cleaners.
Real life port: 6/10
White middle-class college students shall not rappers make.

8. Pacman



Game score: 9/10
Champion of the super-obese, scourge of unquiet spirits.
Real life port: 1/10
The Pac doesn't want or need studio applause, fool, and since when did the ghosts have truncheons?
