Graphics, look great to me, for those complaining about detail, did you not notice that when the last boss bit the barbarian in half, his entrails were strung across the screen and the boss had blood dripping down its chin that left a stain on its chest? That's pretty darned detailed to me.
The runes they showed in the video were call "Lesser Power Runes" and such, which makes me think they'll be a temporary buff maybe? Kind of like the oils from hellfire. We'll know in time, but if they do the runeword system, I would like it to be slightly easier to get some of the runes. I really don't want to have to spend 4564561189486416186484561686 weeks trying to get a drop.
