It can be fun, but I never actually felt satisfied with anything I did in that game. I remember one account I had got hacked at some point, and I had stopped playing it before that happened, but one day I decided to log into it, it said wrong password. So I looked it up, and the stats were like practically maxed out. :O
Well, at least someone put it to good use. :P
*puts on wizard hat*
*plays runescape*
:P
On the topic of MMORPG's, the only other one I think I ever played was Eve Online. It was fun, but after I joined a corp it got boring, it felt like all I was doing was mining asteroids to make moneez. The most fun part was actually just talking to people on there, sometimes I would ask them for some moneez and they would give a few million. :D
I plan on making a game at some point if I can figure out what types of coding I need to learn, and if I do I'm going to make the currency in the game "Moneez". :P
