Oh wait... I forgot one... the "Pseudo-Gamer"" I'll call him, for the meager effort I'd like to give this post...
This type of "gamer" isn't a gamer at all, although he may think he is. His "main function" is his heartfelt obligation to "help" others to avoid any letdowns that he himself has experienced from a dissatisfaction with a game, or one of it's elements.
Sometimes, his "advice" can be truly constructive, as it is indeed heartfelt, but most often, his compounded ire gets in the way, and only leads to his further dissatisfaction with the game, it's elements, and life, in general.
Not knowing how to properly invest his time and efforts into the game, the game becomes but a vehicle, a way to expound his theories of it's shortcomings to others.
While wishing to be "just another one-of-the-guys", for some reason, his propensity to fall back upon his polished sword-of-a-tongue never allows this compatriotism... this feeling of being "wanted around"... and although many attempts are made by this "Pseudo-Gamer" to accomplish what he feels is his duty, those attempts are inevitably vanquished by others who aren't swayed by the sad, vacant look in his eyes.
This type of gamer is not usually prevalent, and finds this "me against the world" attitude to be further befuddling to his psyche... causing repeated attempt, after repeated attempt to justify his crusade against his perceived "enemies".
Hopefully, one day, this type of gamer will be able to see that some windmills are meant to be left standing... some dragons can be left to be slain another day, and it's just time to let go... and maybe find a game to take-up some of his idle, but precious time.
