I've ignored every video, every preview and every review of it. I don't want this to be spoiled, not even the first 15 minutes, not even the INTRO video or whatever. I made that HUGE mistake once with Divinity: Original Sin which dang near ruined the entire first half (10hours) of the game (I was in Alpha/Beta)
I read the backer info we got somewhat, but only general info. I have no idea about races lore or gods or what not else.
I did keep up with it though, and looked at 5 or so screenshots. Everything else would just spoil the first-experience. And as you can see from my post count, I didn't even interact in the forums ;p All to avoid spoilers.
That Obsidian released press copies and didn't give a full NDA to them until release day sucks of course. It means I can't use about 80% of the Internet without fear of spoilers. But then again it doesn't really bother me. Tomorrow I will play the game (hopefully) and all is well and good in the world.
