VNI80: I believe I am somewhat of an oddity among the gaming community.
I think either there is no such thing, or if there is, then most of us are oddities in our own little way. :)
VNI80: I tried playing multiplayer games (Counter-Strike) or MOBA (DOTA 2) and found them boring: they had no story, the Relatively recent I found out that gamers refer to the type of player that I am as a “Single Player Purist”. Pretty accurate, but I feel pretty lonely. I tried following some forums but my sense of loneliness grew even worse: if a game didn’t have multiplayer it was not worth playing and to like a linear game was one of the greatest sins.
Don't get tied up in a label. Games are for entertainment, and entertainment is watching and/or participating in something which generates any number of positive and/or negative desired and/or undesired emotional responses either alone or with others. Ultimately a good gaming experience is one that generates emotional reactions in us that we find more pleasurable and less unpleasurable whether we are doing it alone or with others. If we're not enjoying a game experience it is because we don't enjoy the emotions we're feeling whether they are the result of the game itself, or the result of communications/feedback etc. from other players in the context of a multiplayer game.
So there is no right or wrong way to game other than that which the individual finds enjoyable and entertaining. The labels and judgment of others hold no merit other than what we allow it to have.
VNI80: In a nutshell: I’m a single-player-purist (almost) that plays games first of all for the story they tell, likes linear games (the last I played was Shadow Warrior 2013 and for me was like a breath of fresh air) and who enjoys adventure games and a good Couch-Coop-Campaign.
Am I the only one?
Of course not. The majority of games have single-player mode of some sort in them if the entire game itself isn't single-player only. Look at Skyrim and the other Elder Scrolls games for example, or Fallout or any number of other RPGs. Most of these games on the surface sound like they _would_ be multiplayer games, but most of them tend to be massive single player experiences. The Witcher 3? 200-400 hours of single-player fun.
People play different types of games to get different types of experiences, to feel different types of emotions that meet an internal need. It might be the thrill of the kill, or it might be enjoying some top notch acting or voice acting, getting deeply entranced by a good story and the characters, or it might be by extending your goat tongue and attaching it to a lawn chair and swinging it around your head like a windmill and killing innocent bystanders while you laugh profusely like a 14 year old school boy. Whatever it is that generates the fun and enjoyment for you - do that. If it is a single-player experience then enjoy that experience. If it is gaming in a multi-player context, then try to enjoy that too.
If you play single-player only games alone and prefer and enjoy the games but end up feeling lonely - that's an entirely different problem however, and multi-player gaming may or may not help with that.
I like both single-player and multi-player games, however the majority of my gaming tends to end up being single-player in the end because I strongly prefer to play multi-player only with people I am close to and know really well who are friendly and fun to game with. I avoid online multiplayer games which one tends to encounter others displaying childish unsportsmanlike behaviour, verbally aggressive conflictual behaviour, anger/rage/tantrum players etc. I just can't handle that stuff. I abhor cheaters and refuse to play with anyone who cheats or on any servers where cheating is observed to be taking place.
So, I mostly play single-player games and self-orchestrated multiplayer games with carefully selected players. I stick my neck out of there into the black morass of the Internet for some games from time to time, but usually duck back in before it hurts. :)
