I think you're speaking of different games. the_bromo_tachi refers to the latest entry, 15, which is single-player only. ;)Non-steam ver. is GBP 26 over at CDKeys, this edition has 30 day sub+all expansions up til Shadowbringers.
The non-steam ver. is Free, allowing only 1 character and capping you job levels at lvl. 35, but has no time limit.
