They always say that memories from the past will always come back to haunt us. In this case, it sorta did. The iPhone port for the 1993 haunter, Myst, just hit the App Store, sending a nostalgic chill down our gaming spine. Here's a video to refresh your memory.
Naturally, Myst will make use of touch screen as the interface, as seen on the frequent appearance of a big black finger on the video. Since the gameplay would revolve mostly on exploration, you'd literally have to do a lot of poking around - poking interesting objects, poking on little corners and such.
Like the heavy mist on the creepy island, Myst is a rather heavy 727MB because of all the art, video, and sound effects in the game. Myst is currently available at the App Store for US 5.99.
How about another iPhone game?
