Generally speaking I’m a mix between Achiever and Explorer, though more inclined towards achiever.
I don’t really play MMORPGs at all and the multilayer games I do play tend to be shit like battlefield or chivalry so I don’t think these categories would apply much there, but for the ones I used to play (such as ye olde Runescape) I was an Explorer (used to love going to that wild land thing to the north where you got fucked up by anything you come across just to see what was there).
On games I frequently play such as Fallout New Vegas and Fallout 4 I am mostly an achiever, I always want to do side quests to see more of the game but very soon I veer off into doing the main quest because I want to complete the game, even on replays (and believe me I have a lot on these two lol).
As for something like Metal Gear Solid 5 I think they really tried to appeal to achievers and explorers by making it open world and literally showing you the percentage of game completed, then giving you lots to try and do in a mission to complete it, as well as side ops. They don’t like killers (muh demon snake) and socialisers are crippled (if you really want to count FOBs and MGO as socialisers), this is probably one of the reasons why I consider it one of my top games of all time (controversial I know).
Even in a game like Civilization I’m an achiever - I pick the Civ I want based on the victory type I want and basically focus entirely only that for the game, meaning I only really become a “killer” if I choose domination lmao, I don’t interact with many game mechanics outside of “what will make me win”.
This is quite an interesting video considering at an abstract level most people just consider gaming a relaxing pastime and base player actions on personality, but the psychology of simply how you play a game is very interesting in itself.
Even as I type this I realise even chivalry fits in this afterall - achievers just want to play and be top of the leaderboard, explorers want to find vantage points on the map (usually glitches), socialisers just hang together and talk in the text chat instead of actually playing (or just decide to duel), and killers just go round and kill without considering the other options (basically an achiever who doesn’t care about the socialisers and thus doesn’t leave them alone lmao).
