I'm just thankful they don't rush and end up screwing us out of content or quality. They make games the way they should always be made.

As good as some "clone sequels" can be (Resident Evil 5, God of War II, etc.), it's very refreshing to have a game that simply stands alone. These games (Ico, SotC) appear to be very artistically influenced. Art isn't just defined by what you see or get, but what you don't see.
My point is that if you have a great game (or score, drawing, whatever you're doing), it needs to flow naturally. Video games tend to lose that natural flow because success tends to drive sequels, as opposed to the passion that drove the original. If you overproduce something and keep throwing money at it, you can never replace the passion that was poured into an authentic artistic experience. I think that's why truly good games are so few and far between these days.
