And this is pretty much false. Guild housing is definitely accessible at the entry level in most other MMORPGs. The problem is exactly that there's no entry level on FFXIV's legacy servers.
It's not pretty much false, i've played multiple MMOs with difficult to obtain guild constructs (houses, airships, etc- the latter in DDO) The only game ive played where any form of housing is "entry level" is FFXI where everyone starts the game with it (but it is comparably simplistic and for a long time was completely private).
