Like so many of the new things coming this Fall, it is not on my list. This will be the first LOTRO expansion I have skipped, but I am so far from the content, still being back in Moria with my highest level character, that there seemed no point.
I will, however, be looking into buying that extra bag slot with my accumulated Turbine Points. I get 500 every month for being a lifetime subscriber, so long as I log in… and I make sure I log in at least once a month.
Of those, I am only really signed on for the Storm Legion expansion for Rift.
And the EVE expansion of course. But that is more like a patch update, not something I have to go out and buy.
