- noun The impression of the dimensions of the world
modelled by a MUA, as perceived by the players. Normally, this
correlates pretty well with the number of rooms it contains,
although if large quantities of maze rooms and hard-to-get-to
rooms exist then the MUA may well feel smaller than the raw
data would suggest. Some MUAs work on a co-ordinate system,
where a 100 by 100 grid can generate claims of "10,000 rooms!";
normally, these games allow personae to interact directly with
one another across several (eg. 5) room boundaries, which makes
them feel less vast. Size (or, worse, number of rooms) is
considered a Good Thing by people who know more about SUAs than
MUAs: in MUAs, what's important is the players/size ratio, ie.
how long you have to wander around before bumping into someone.
It's no use having 5,000 rooms if there are only 4 players, as
contact would be so infrequent that the MUA would feel empty.
Likewise, 200 rooms and 20 players would certainly be cramped.
