I know complaining about Runescape has been cliche for the past 10 years but I think my complaints are slightly different. Runescape (3) is so different from the 2005 game I started playing. People like to complain about things like combat, which I agree is broken, but I have nothing unique to add to that conversation.
Other things maybe I do. For one, the story has jumped the shark. I never cared much about the story but the past few years I have been paying more attention due to writing quest guides or checking quest guides and this has stuck out. For one, there are clear organization issues. There does not appear to be a definitive storyline the developers are following, and interesting developments that could lead to something are scrapped by the next quest in the sixth age storyline because some other developer wants to take it in another direction. Also, the villains keep getting more powerful and everything else, like some missing artifact from an earlier quest, seems unimportant. Now we're dealing with creators of the universe and there's nowhere else to go. Why can't we go back to saving towns from evil wizards?
Besides that, the biggest change has been the community. Back in 2005, it seemed to mostly be populated by casual gamers. Everyone was in it for fun, your average person didn't care too much about training skills to as high as possible, etc. People also played less. Then, a casual player of Runescape would play for a few hours a week; now it seems a casual gamer plays a few hours a day. As someone who has time for maybe 2 hours a week this is a fairly unappealing aspect. The rest of the community is completely different than I am and they are driving the game in a direction I dislike. I'd prefer to go back to playing Castle Wars instead of trying to go for 120 capes. And, to reiterate something people say all the time, the SOF costumes completely ruin the feel of the game. It would be different if there was some way to disable those features, but Jagex doesn't want to do that because the reason people buy those costumes in the first place is to show it off to other players, even if the other players don't care for it.
I think the core of the game is still good. Walking around places that have been fairly untouched, such as Rimmington, is still moderately enjoyable. Other newer features are not as appealing to me. This is not a quitting post but if it weren't for connections I've made in the game I would have probably left by now. The only Runescape version that still interests me is RSC, but that is not in great shape.
