So if you fought Damian at the end rather than Ygerna, it would have been a good game?
You do realize in any series of games, if you defeat the main badguy in one game, then in the next it will turn out he wasn't really the main badguy, an evil apprentice will take over the organization and be just as bad, a cult will form dedicated to resurrecting the old badguy, or other badguys you never heard about in the previous games will rush in and try to fill the power vacuum left the death of the previous head badguy?
Were there videos showing the player character transforming in Broken Valley? Refresh my memory...
There was originally a Broken Valley type area in FoV (shown in the background of the DKS website), but doing everything would have delayed the release by the better part of a year. During development Larian figured overall the game needed a central hub of human activity more than it needed another dragon area, so that is what they focused on.
Larian has two more RPGs in development, scheduled for release next year.
Have a nice day yourself (hopefully you've calmed down by now and gotten over your tantrum).
