Having just opened Metacritic, and looked at all the reviews for 'ICO' and SOTC, it kind of struck me how they all complained about 'bad' controls, simplistic puzzles and gameplay, being repetitive and all (and one hilariously , if sotc only had more zelda stuff in it-review )
and yet most of the reviewers said its amongst their best games ever (for that time)
For me personally, i hope it will be too. everything ive seen so far makes me, "i just want to play this"
But my biggest fear is that it will be totally trashed in today's media. Media that will not understand you are playing with a beast that doesnt listen all the time (atleast one review will mention its downright broken) , it will be fuel for xbots vs playboys in the flamewars, like NMS (its the worst game ever and you are a tool for liking it - and i like the game very much ;| ) ...
...and prolly hailed as one of the best games in 5 years from now, for its experience.
