My notes on the article by Richard Bartle players who suit muds

He talks about mud's but what are mud's , he says these approaches arise from inter-relationship of two dimensions of playing styles : action versus interaction and world orientated vs player-orientated. He says the analysis hes are labeling for mud's.He says that Trubshaws 1978  game Bartle 1990 and Burka 1995 he says because they were inherited the majority are regarded as games by the players.he explains the types of games and what type of game it is.he talks about the dynamics of games and how to keep the game balanced with simple methods example: to increase number of achievers reduce the number of killers , but not by to much, so if you have 200 achievers then you should have 150 killers and if still 200 hundred add 50 to keep it balanced. In the article hes explaining how to a game balanced with simple actions of change so the games stay fun and  not overdone.
