Ooh, splendid news! I thought KotC was still some months from release. OK, need to quickly go home from work and start downloading the demo!
Hopefully the resolution issue won't be too much of a pain (i.e. headache inducing). Can't you play it in a window and thus slightly mitigate the blockiness (and the like)?
The font is something I don't much like either. If the game had featured lines and lines of text it would've been a major issue, but I estimate from the screenies, that the text is mostly given in smaller doses in KotC, so maybe it is at least tolerable. Oh well, I'll see for myself soon.
