Games that put the player in control of a mech (or a similar type of giant robot) have waxed and waned in popularity over the years, and have come in many different varieties. These days the Armored Core series is arguably a standard in mech games, having been around consistently since 1997 on the original Playstation. It was not, however, the inventor of the genre. Many would consider the inventor to be the MechWarrior series, which debuted on MS DOS in 1989 (and the Super NES in 1993). These were certainly some of the first games to place the player inside of the cockpit of a mech, presumably replicating the slow and lumbering feeling that one would experience from trudging across a battlefield in a giant robot that is not really all that mobile. Even the most popular entry in the MechWarrior series, MechWarrior 2 was released two years before Armored Core in 1995.
