Alright, I just gave The Sands of Time a chance and played it. It was difficult at first, as I was accustomed to unreal engine shinyness and now tumbled back into 2003 graphics.
But I have to admit I thorougly enjoyed this game (apart from the combat system, jesus, if you ever played that elavator fight, you fucking know what I mean). Especially the story got me, which surprises me considering how incredibly cheesy it is (spoiler alert: and thinking of it now, wasn't the ending the same kick in the nuts we received from Zelda OoT?)
Why am I digging up this old thread? Because I want to know if it is really worth playing the other 2 games. It seems they are not as good as the first and I don't want to go through the same mindfuck as, lets say the movie "cube", where the sequels destroyed all the experience of the first part.
