What keeps you playing RuneScape?

I think attempting to max out keeps me coming back. I've been able to quit for 1 and 1/2 years at one point, from 2006-2007 I didn't touch RS. I noticed when I came back just about all my friends were near maxed lol, that's kept me playing pretty much up until now. Just trying to catch up with them although a few of them have maxed and quit playing now. I know one returned to max DG, the others haven't returned yet since DG came out.

In my last clan I took breaks but never went retired or took clan friend because I didn't want to "start over" getting ranks and seniority in the clan, since obviously if you retire someone has to fill your old spot. So, I still played but only enough to keep up with attendance reqs. Outside of doing 1-2 events a month I didn't play at all for 2-3 months at a time.

Every time I do return I think it's because I believe I am ready to max out but than I get bored again and slow down to a point were I eventually stop, usually happens after 99's or after training a skill a lot in a quick time. I just burn myself out and I don't have that urge to play anymore. Usually I just need a quick break though before choosing the next skill to train.
