I have recently completed DKS and I just feel the urge to say how much I've enjoyed the experience.
There are some things I don't like; things that made DKS not one of my favourite RPGs of all time, but the overall feeling has been extremely positive.
The first part -Ego Draconis- has numerous flaws, but at the end it felt as an epic adventure. Flames of Vengeance, though, is a masterpiece. Playing both in sequence gives a gameplay-rpg experience far superior to almost every RPG out there.
I sincerely hope yopu keep this good work, since lately the genre seems to be fading into some kind of Beyond-the-call-of-honour dragon-boobs-awesomeness thing. So, again, thank you; DKS is the best game I've played in the last two years.
