According to a quick conversation IndustryGamers had with Silicon Knights' Denis Dyack, the company still has plans to finish out the Too Human trilogy despite the lackluster sales of the first title in the action RPG series. They'll need to wrap up their lawsuit with Epic first, though:
Silicon Knights President Denis Dyack told us, "We intend to finish the trilogy but no comment beyond that... You know, there's very public litigation around that."
Dyack, of course, is referring to his ongoing lawsuit with Epic Games, which he claims provided less than complete Unreal Engine code, and so Silicon Knights said it had to rebuild the game's engine. For its part, Epic maintains that it will be "fully vindicated" in court.
