It's a huge dose of nostalgia this week on Mobile Monday. Developers have been porting classic games to the iPhone/iPod Touch for some months now, and two of the latest to hit — Myst and Wolfenstein 3D — practically gave birth to their respective genres. I remember when running either of these games required a top-of-the-line computer. Now my music player can run them!

G - Quite possibly the shortest name on the iTunes App Store, G is a game constructed around firing missiles in space in order to "ping" targets placed around the screen. Gravity beacons pull the missile off its path, so your job is to predict where the projectile will go and adjust the firing angle, launch power and firing duration to compensate. The story and visuals are remarkably complete, especially for an arcade/puzzle game of this nature.

iso - A falling block puzzle game that adds a little flavor to the classic genre. Groups of three blocks descend onto a number of platforms sitting at the bottom. Tap the screen to switch the blocks order, and swipe it left, right or down to nudge the blocks in that direction. The goal is to make groups of three like-colors horizontally, vertically, or diagonally. Setting up chain reactions is the way to go, and as you play, the game gives you a bigger variety of colors to make things even more difficult. The online leader board is a nice incentive!

Myst - Yes, the Myst. The first, the classic, the graphic adventure video game that launched countless copycats and was the best-selling computer game of all time until it was knocked off the throne in 2002 by The Sims. Now, the point-and-click game is a touch-and-tap adventure with a deep, intriguing storyline, brilliantly conceived puzzles that are every bit as grand as they were in 1993, and a strong emphasis on exploration. The still images show the game's true age, but this is the kind of game you get so involved with everything else just disappears. It's a bit on the heavy side, weighing in at a healthy 727 MB, so be prepared to wait while it downloads or syncs from iTunes.

Wolfenstein 3D Classic - It's the original Wolfenstein! The game that (arguably) made first person shooters popular has returned in all of its 1992 glory! Using a highly-customizable control set, control William "B.J." Blazkowicz as he attempts to escape from the Nazi stronghold. Attack dogs and armed guards make your life more difficult, while hidden rooms, med kits and weapons give you a much-needed boost. The game may be a bit low-tech for modern gamers to fully enjoy, but nostalgia junkies will swoon at the thought of carrying this game around in your pocket. The free Wolfenstein 3D Classic Lite is also available.
