Immersion

Games are often judged on how immersive they are, and how well they draw you in and make you believe you are a part of its worlds. This goes especially for roleplaying games and computer games. However, sometimes you might feel you've immersed yourself in a game world too much, such as when you consider whether an action is worth risking a life point or not, or you expect to gain a decent amount of experience points for a night out on the town...

... and of course, sometimes you go too far... seriously...

but then again, I never did get into the Myst series
