cheap osrs gold worlds over time - they've decreased the number of pvp countries to just two. DA tournaments- The previous one was removed, but was replaced with a slicker crap, which also isn't as effective. The changes made it difficult to conduct certain activities. Player owned shops- Shop sections of forums, and businesses thrive money making for many people. The rune-based business model is an excellent method to earn money.
Duel Arena - A way for people to make big money or even lose a lot of money. Trading- Self explanitory. Pking- Self explaining. Merchanting- Once existed, pretty self explanitory. Still possible but not very practical. Hotspots for trading such as Varrock, Falador and all five of the worlds were always packed with traders from different regions.
I have just thought of a way to train more than one skill to 99 and at the simultaneously make a huge income from it, based on my experience. I have a goal of creating 100k+ yew-longbows by hand, and getting 99 Woodcutting, Fletching and Mage. What I'm looking for are "supplies" that are: Make 100k+ Pure Essence and then turn it into Nature runes.
When I have all my osrs buy quests in hand, I will flytch my 100kplus longbows. After that I will then high-alch my longbows. I will be rewarded for a job well-done with 70+mil plus three 99's. That is pretty good. I want to hear what you think about my goals. Please leave your comments. My Woodcutting level is currently 96 to get a yews/hour ratio. I'm not sure how long it will take. It could be over 4 months... I hope not.
