Eh, Dune got a big update recently, so got this to support the devs.
You get an Ixian wife that will support and love you.
Although she is Bene Gesserit, so the latter is debatable, plus we already have Jessica.
Ultimately though, the faction is a fun one for big knowledge (can easily get it to 100 late game), some nice assassin plays and a main base threatening deathball (which can easily be countered by EMP bombs - Shh.. Don't tell anyone). Their expansion is also unique and they harvest spice much like the Fremen.
Overall, got my money's worth, as it gave me a solid extra 15 or so hours, and will add more to come.
