Guild wars was good because they were experimenting with a lot of new ideas for MMORPG, some worked and some didn't. (I like the interactive minimap)
I got into GW toward the beginning (it was my first MMORPG) and I got rich off something that was somewhat like a scheme, but not really.
--I bought rare weapons for dirt cheap from players who didn't want to sell them (like 1-3k each) and then I turned around and sold them to new players at high price 10-15k--
I made my first million in about a month. It was real easy. Then the first expansion game came out and it killed my business.
After a bit I fell out of GW, but when Nightfall was released I got back into it. Nightfall rocked and was definitely worth playing (you get to ride wurms and tear apart armies of enemies...armies.)
But after awhile I stopped playing it again.
GW2 is suppose to fix a lot of stuff.
For one you can now jump and swim. The world will be open much like WOW and not your own personal game like GW.
They also have multiple races now, not just humans.

Anywho, if anyone has a char on GW, I'm still rich on it and willing to help out...I don't need all my money. I have like 400k still and my char is just sitting there...
