Other games available on the Mac App Store have been previously released on the Mac, either through Steam’s service or via a native release. PopCap Games, which specializes in addictive puzzle games, has released Bejeweled 3, Peggle, and Peggle Nights on the Mac App Store after previously bringing the titles toSteam. But Plants Vs. Zombies, a popular tower defense game that has been released on the Mac and iOS previously, is curiously absent from the initial releases on the Mac App Store.

Other independent games that appear in the store include Hothead Games’ Precipice of Darkness episodic role-playing-game series, which is based on the Penny Arcade web comic. Initially released in 2008 and ported to the Mac in 2009, each title is selling at a reduced price of $4. Precipice of Darkness, like popular puzzle game Zen Bound 2, paper-platformer And Yet It Moves, and dreamlike physics-based Osmos all make the jump from Steam to the Mac App Store.

Her Interactive’s Nancy Drew and Anuman’s Dracula series also make appearances on the Mac App Store, helping to round out the selection of games with entries from the adventure genre. The Nancy Drew games have been appearing on the Mac for years, but Dracula 3: Path of the Dragon, currently on the Mac App Store, was previously on the iOS for several months and was ported to the Mac last October. The adventure genre is well represented on the Mac App Store, with Women’s Murder Club, The Mystery of the Crystal Portal, and Midnight Mysteries—Salem Witch Trials all appearing among the initial releases.

PlayFirst’s iconic restaurant-themed time-management Diner Dash series makes an appearance on the Mac App Store in the form of Diner Dash 5. The visually impressive steampunk adventure/first-person shooter/time-management game Guns of Icarus also makes it way on the Mac App Store, as does the equally intriguingly-named Gratuitous Space Battles—a sci-fi tower-defense/strategy title with some impressive visuals married to a unique approach to gameplay.
