I played from 06 to 2010 and built my guy up the hard way to lvl 138. I had 14 skill capes (slayer my fav), quest cape, and fire cape. I had pretty much all the money I wanted, just never enough (or soon enough) to get a party hat.
I stopped playing because Jagex was making the game easier and easier for the whiney kids. They didnt want to put the time in for anything or complained all the time that something was too tough to get or wasnt fair. And for some reason Jagex just kept listening to them and continued to find new ways to make the game easier for them.
I could go on and on about how the game eventually became a let down for me but it was over all one of the funnest online mmo games that I've ever played. I'd still be playing it today if it wasnt for the "dumbing down" or however you call it.
Jagex made a lot of the training easy but they made the combat harder. Like Nex, I think she came out in 2010 actually. She is level 1001 and can easily destroy any player if they are not ready yet. Also, got the Dominion Tower now. That is a fun thing to do cause it allows you to re-fight quest bosses but with a twist.. If you play ladder mode, you can get special effects that helps you or cripples you.. Some of the good effects would be a healing one, which is like free food basicly and stun monster which will make the enemy randomly stunned and can't do stuff for a few second.. Some of the bad stuff is weakened defense, you start with half of your health, poisoned, diseased, random freeze (Really annoying), etc..
I have to say Dominion tower is prolly my favorite minigame. They also added a special boss to. I can't remember her name but she is like a level 500-something Magma Dragon and has a lot of special moves like she can fly around the arena, making it impossible to hit her, and do dive bombs making rows of fire in that area. She can also set half of the arena on fire. (The fire does constant 50s, I think).
There is also this one special match that is hard to do.. "No Nomadness No More" <-- This match is basicly, you fight Nomad.. 2ce in a row with only one inventory...
I am rambling now..
