I began playing RuneScape about 5 years ago. Back then, there were only 3 worlds (not 70 or however many they have now). My username was "Krazymonkey5" -- I have a couple stats obscenely high leveled, and was once an admin on a 10,000+ member RS community.
I quit as soon as the following three changes occured (this happened over a span of a couple years, actually):
1) The chat program was parsed in a completely messed up way. I.E., sans exception, all text was changed so that the first letter of sentencs was the only letter is capitalized. This led to stupidity like "Yes, i am insane steve." The censor was also messed up. For a period of time, I remember when every so often almost every character in a chat line was starred out because the program found it obscene. I still think the filter is horrible.
2) The graphics changed. I liked the quaint, almost Paper Mario-ish psuedo 2D character graphics - then they changed to 3D everything. Which I didn't like, although that isn't the worst part... after this, they decided that added a bunch of horribly stupid content, like being randomly attacked by bees, was a great idea. Those random events annoyed me enough to quit.
3) Playerbase went down the toilet. When there were only a few servers, the people in game were helpful and didn't act stupid. I log on about 5 months ago after my year hiatus and discover that like 90% of the playerbase wants to buy my Santa Hat for 10% of its market value, and that they all claim that that's what it's worth although the rare market and market guide on that community I was once an admin on say otherwise. Then they flame me out as a "stupid nob" -- even though, as I said, I've been on that game since it only had 3 worlds. Then again, I realise that the less esoteric a game is, the more likely the playerbase will be full of idiots. Just how anything is, I s'pose.
So, ya. Game became unenjoyable and I gave up.
