With Temple of Elemental Evil, Star Wars KotOR and NWN's second expansion pack all coming out for Christmas, I think it's a good job RiftRunner is not going up against them.
I'm sure not everyone who will buy RiftRunner will play all - or any - of those games, but I for one will be buying them all (just as soon as I upgrade my damn PC...)
And if RiftRunner does come out when things have calmed down it stands a better chance of selling well, which is what we all want.
Take ya time, Larian...
