Yeah thinking of canceling mine too. I haven't tried the BETA myself but I hear bad things. Maybe I'll wait till some reviews come out or until they patch the game a few times. I'll have to think about it.
I had poor experiences with the beta as well. Very pretty graphics, but that's about the end of the positive remarks I've got.
I haven't played any FFs since about 4, so I really had no expectations going in. The beta site is so screwy I couldn't even post bug reports - every time I log in, I'm a different username, and as soon as I click most of the links, I'm directed to log in again.
The beta downloader speed is abysmal (not sure why, frankly). Lots of posts telling you to port forward, so I did that, and still could only get ~10k/sec tops. Also, mouse lag - even in the beta downloader - is HORRIBLE.
Finally found mirrors, installed from those files. Again, terribad mouse lag (I saw someone here said they disabled hardware mouse?). Beautiful opening cinematic, leading to my character running into a forest clearing, where I've seen a couple people fall from a smoking airship that streaked across the sky.
They're both unable to speak, so I run around and don't see that I'm able to do anything for them, don't see anything I can select or use on them. Try to leave the area, I'm teleported right back in front of them.
Clearly the game's trying to tell me I'm supposed to do something with them, and while normally I'd be intrigued by the mystery of how I can help them, I was just totally turned off by the 1+second mouse lag.
Uninstalled and here we are.
