I recently did the same a few months ago. Bored, with nothing to do on week nights, so I got my membership back again. But in all honesty the game isn't half as good as it was. I personally blame real world traders forcing jagex to remove the wild thus making the game worse. Also I came back as a level 110. Level 110 when I quit was considered a decent level, especially having 92 hp meant that my account had been trained properly. Now I'm probably low level with the release of summoning (IDK what the hell it is or how to train it TBH) And i have no idea what any of the new equipment is/does and I have no intention of finding out. But I can still play, not half as obsessively as I used to, but I can still spend an hour or 2 a night on RS. I'd recommend that you carry on with your old account, I considered making a level 3 with a better name. But I decided what's the point? In 6 months time you'll probably regret starting from scratch and think "my account could be level 100" or whatever.
