This game from what I've read on different sites is a huge disappointment. Myst was originally one of the first killer apps for CD-ROM and is a point and click adventure game with static environments. Basically one of the best adventure games of all time. So when I heard it was coming out for DS I put this at the top of my want list but after reading a couple reviews I'm not so sure that its worth it anymore. Check out these 2 reviews to see what I mean:
IGN: Myst Review Myst for DS Review - DS Myst Review
The guy at IGN seemed like he didn't like Myst in the first place which makes him a crappy choice when picking someone to review a game so I sought out gamespot hoping I would see a better opinion when they gave it an even lower score.
Anyways like both of these guys said maybe it is time for Myst remakes to die as it has been released many times over the years and I'd rather not see its name tarnished. It'd be great for one of the more recent Myst games to be ported (there are 5 games in the series).
