This is awesome. I had never explored the Alpha client before. +4 rep to the OP for awesomeness.
So, Ironforge is amazing... love the 2-level concept with the bridges. I also went to Karazhan to see how that was originally, and that was wicked as well. (any way to get up to the tower? Seemed to be floating...)
What other areas are "like this" in the Alpha client that I must check out? ie: big changes like Ironforge from Alpha to initial release that I would really want to see for myself? Obviously I'm checking out the developer and strange island areas, but I'd like to see the public things like Ironforge and Deadwind Pass etc. that are out in the open but have been completely changed.
*edit: I've actually never explored ANY other client before... is this how it all works? You just find downloads online like this and boom you're playing private versions of WoW? Is this forum full of worlds like this? What is the difference between emulation and private servers? And where does model editing come into all this? Man, I've only been exploring live... I feel like the rabbit hole goes so deep it seems intimidating...
