I was thinking about doing it... I've seen a few youtube videos about it and it looks solid (to say the least).
Just a few things I'm worried about:
A- Viruses. I already (mistakenly) infected my desktop with various viruses, and I'm NOT doing that to my Mac....
B- Speaking of Macs, I wonder if I can run it on this machine
C- Overall quality. I've been staring at it for quite a while, just itching to get into the action. I mean, it looks like there's not a lot of people using it... so it won't be like Runescape (which I hate...).
So pretty much, I'll do it if you do it :).
EDIT: OK, so I tried to download it yesterday and... meh. First off you need this Zango thing or whatever, which is a lesser copy of AIM or MSN. Then you need a copy of Virtual Boy or some sort of application for it (obviously), and A.) I can't find a newer version for the Mac and B.) I don't want to get more viruses (unless someone can PM a good one... then I'll try it again). Finally, the file itself SEEMS pretty safe, but I won't know for sure until I can actually play the game.
