I consider DC 2 one of the most boring and overrated game of all times, I still regret the day I buyed it... (never been able to go too far after the sewers... maybe I gave up too early... or just not my genre)
DC 1 was a little better. but nothing memorable...
BUT
I would be still curious to see how they can improve the formula and make it more appealing nowadays... and I know there is a little fanbase of it, so I still hope for a third installment... (still I think games like DQ:Builders are an evolution of what DC was after all...)
