Although I may be wrong, it seems that RuneScape gold Jagex gives more thought to Treasure Hunter/Solomon updates than regular game updates. Many of the items released could have been utilized for a new quest or skill improvement. Forges that can be carried around and ranges are particularly useful.
Quality over quantity I guess? However, it's not really. This indicates that 2005 was either poor quality or today is great quality. This year's quests - One of a kind - Okay. It ought to have been rated Master rather than Grandmaster. The game is also rushed. Recycled graphics are used in the new zones (celestial Dragon Dungeon is the same place as the Brimhaven Metal Dragon Area).
Fate Of The Gods – Very good / great. It's well-crafted, but not too contained. Shadow Over Ashdale - Novice and short, but a good atmosphere. The Mighty Fall – Pretty Good. Plague's Ende - Some portions were great, but they were rushed.
Two are unfinished, and three are great. I would say that late 2013 quests are more time-consuming than other quests. Birthright of the Dwarves was the most notable example, with no Post Quest Dialogue available until Plague's Ende (almost an entire year).
2005 quests: I can't find a full list but here's some I've found. Desert Treasure – Very good. Part II of Mournings Ends: Immersive - Not one of my favorites, but for obvious reasons. Rat Catchers The video is lengthy and sort of humorous. New areas have been added. Swan Song - New Area with a great boss fight. And 20+ more quests, none of buy old school runescape gold which seemed rushed.
