Fifteen years after the original Myst released for home computers, it's hard to remember what an incredible phenomenon the game had been. The adventure genre had been reshaped by the innovative use of a first-person view, and many had rushed out to purchase cutting-edge "CD-ROM drives." With millions of copies sold, it still stands as the best selling PC adventure game of all time.

But what was behind the frenzy? Empire Interactive wants DS owners to find out later this month (PSP owners will have to wait a few more months for their port). The entire game is controlled through the touch screen, an obvious design decision considering the hardware's capabilities. Point and click now becomes point and touch -- however, expect to have a bit more difficulty with the handheld version. When using the mouse on the PC, players knew what they can click on by the shape of their cursor. There is no on-screen representation of your stylus, so players will have to simply use their intuition to click on the appropriate items.

There are a few new tools for players to use, however. There's a clever magnifying glass, which allows players to zoom in on objects in the game world. You can even take snapshots of your screen and save them, recalling them for use during a particularly tricky puzzle. There's a map as well, but it won't indicate where you are. Finally, you can save notes, typed via virtual keyboard (no handwriting recognition, sorry). These additional tools should make navigating the game's tricky puzzles a bit less daunting.
