Absolutely interested in the game, especially since they also plan to release it for PS3. I agree with bloody-hell, though, these graphics are a no-go these days. Dungeon Defenders is the reference for me, graphics-wise (detail, not necessarily style). It shows what great game you can make for $14.95. If this game gets a little work over (and some online co-op?), along with a decent price tag and a platinum trophy list, I'll go for it.
A new dungeon keeper like game was way overdue, so this is very welcome. At 01:40 in the video the dwarfs walk in place (playing walk animation while standing still) and when turning, the turn animation plays too slow. At 02:00 in the video the patroling dwarf AI looks very dumb, running into the Ogres, getting killed, so I hope this was just the most basic form of AI and that they are still working on it before release. I hope there's lots of interesting game mechanics, not just digging and expanding For a Q3 2012 release it looks very unpolished, but the video in the background could've also been from an earlier build so they can show at least something. Seeing that it's Paradox fills me with joy, knowing it won't have any form of DRM - I support that and if the game doesn't suck they get my money, no questions asked.
