I picked up Castlevania: Portrait of Ruin on Tuesday and after playing it a little, have found it really good, if not very similar to Dawn of Sorrow.
So far I've defeated the first few bosses and apart from having two characters and less touch screen compatability, PoR is pretty much the same in gameplay to DoS. This is not necessarily a bad thing...as DoS was a great game for the Nintendo DS, but a little innovation may have been nice.
This brings me to my next topic...innovation. And the heaps of sequels which land on our gaming shelves each year. I am the first person to admit that I cannot wait for a host of sequels; MGS4, GTA4, SSBB, FFXIII and the inevitable sequels in the Zelda and Dragon Quest series. Hell, I even find myself hoping that they'll announce that Metroid Prime was a quadrilogy and not a trilogy but at the same time I crave new types of games and new ways to game in.
I guess what I am trying to figure out is, how much of a good thing is too much... and when do developers decide to clean the slate of an old IP and try for something completely new and revolutionary (Bioshock, Assasin's Creed). I believe that the answer to this question is becoming almost the holy grail of gaming. Because without innovation gaming will stagnate...but if we abandon our favourite series and our old ways of gaming we may never enjoy playing games as much as we have again...
A leap of faith is what may be needed from the gaming community if we are going to completely change the way we play video games, but it is one which the community may not yet be able to take. For now I guess we can hope some daring developers can continue to push the envelope and find new ways to entertain while we continue to play as our favourite characters at the same time. Because as much as innovation excites me, I know I can't wait to take Solid Snake on one last mission to bring down Metal Gear...can you?
