So I've come across a bunch of people on the Internet (proper noun) who are using the word 'addicting' to describe the properties of video games. This underscores a fundamental lack of understanding of the properties of adjectives. 'Addicting' is not the word these people are blindly groping around in the dark for, and I will now explain why you should all be using the correct adjective 'addictive'.
When applied to a person, the adjective 'addicted' describes a physiological state the person experiences. A person is imbued with properties objects do not have (by virtue of being alive), and this is reflected in our lingua vernacula. When applied to an object that same adjective names or describes a property of that thing, and this is reflected in a modification of the word. So a person can be addicted to video games, and video games can be addictive, but neither can be 'addicting'. This is because 'addicting' is not a word. It has not yet been published in a reputable dictionary because you cannot use it in a sentence without sounding stupid.
Consider the nonsense; "I am addicting to video games." or "I find video games addicting."
Now consider the sentences; "I am addicted to video games." and "I find video games addictive."
Clearly the former makes one sound like a resident of Hicktown, Nowheresville. The latter, on the other hand, conveys a certain sense of cultured propriety. A knowledge of how to use words to convey a sentiment we can all understand and agree with, rather than nodding our heads in the knowledge of what was actually meant, while tittering behind our hands at the sort of lexical inflexibility arrived at usually by the wilfully ignorant. The implication is not that people who use the word 'addicting' are the poorly educated denizens of Nowheresville! Just that they are perhaps so addicted to video games they find it difficult to pay attention during English composition class. Kids, don't play video games! Stay in school and do drugs so you don't wind up making this sort of mistake.
"But consider the common usage!" I hear some reasonable voices among the gaming community cry. Well, I do, but in this regard, you can be respected on the street for your idiomatic speech, or you can be respected in the literate upper echelons of Audobon gaming society. Use whatever form you feel is better for the circumstance, adhering to linguistic convention or detaching from the ordinary both suit different states of mind. But even if it's full of very interesting ideas, you won't get your article on "the addicting properties of gaming" published in any major journals without major consideration to editing.
