Well, I'm a member too. I started like 2-3 years ago when the community was much better, but still, I'm hooked. I can play more MMOs, I have GW, and have tried most other f2p MMOs, with a few p2p on the top, but for some reason they all we're out of my computer maximum a month after install. Anyways, yes, the graphics suck, on the free version (and part of the members). It is pretty amazing to see what there is in the latest updates, Including plenty free monsters that were updated and the latest quest, wich rocks
Anyways, let's compare. 5$ for a game, 1 update a week (except like 1 or 2 times an year), nice playability, the worst part of the community is f2p, so you wont hear about the "noobs" a lot (I don't), while on a normal game it's minimum 10$, sometimes the game even has a worse playability than this one and less features (Memebers world has so much stuff to do...) so you're actually only paying for better graphics and music... (There are some exceptions tough, none kept me hooked long enough tough)
Guildwars was the only game other than RS that hooked me for 2 months, due to it's innovative style, but other than that... I just unninstall it.
Just my 2 cents.
