Honestly, once you get to about level 50-60, buying Unids, making potions, selling unused herbs, and selling potions is the best in my opinion. I got to level 78 this way and also made a few mil along the way.
The Games Room has no real reward. If Jagex offered special clothing or new weapons or something for reaching certain amount of points, then people would flock there.
I was on my way to do some Solo-KBDing. About half way there, I suddenly see, literally, fifty white dots come in out of no where. I get hit with about thirty binds and ice barrages. I was dead in less than a second. Lost about 400k in stuff :(
Jagex should add an IQ test required to create an account. It would just about stop most new people joining the game it would seem.... Best idea ever. People at lizards are just horrible. I'm there using one little tree. A level 125 comes along and starts using the other two. Then, he starts going for mine. People are being so horribly selfish. I know everyone wants to raise their levels, but I'm disgusted at people and how they're acting.
Only thing I'd question about the winners is originality. No offence to Oreo or MrPez, but I see outfits either the same as or very similar to yours' a lot in RuneScape.
