Guild Wars 2

It is unsupported “at this time”. It will most likely be supported some time later.
Not everyone wants to/can upgrade to Lion due to software incompatibility. :B

I’ve done so. :) Thank you for the reminder, though.

Exact same problem as Lucid, here. :)

My experience is as such:
I have downloaded the client, installed and patched it without any kind of problem.
When came the time to hit “Play”, I did so and ended up on a black screen. I had to reboot my iMac to be able to get out of it.
I tried again several times. I had to reboot once again, but the other times, it simply got out of the black screen by itself, showing an error message, but not long enough for me to make note of it.
Finally, after trying a few times, it let me into the game. I’m not too sure why it even worked this time.
However, if I get out of the game, it takes another several tries to get in again.

Once inside the game, though, I haven’t yet encountered any issues.
My framerate was around 30 with Antialiasing on and most graphic settings on medium.

That summarizes my experience so far. :)
