The Houston Area Arcade Group, or H. A. A. G., is an annual gaming expo based in Houston, Texas, U. S. A. and was founded by Keith Christensen. Its first show was on May 25th, 2002 at the local Fitzgerald’s music club. 52 arcade and pinball games were slated to appear, all set on free play (after an attendant paid an admission fee), along with a Tron and a pinball contest were also held. People could also buy, sell and/or trade games, along with tips at a gaming clinic were held.
The show has since grown to having up to (or over) 400 standalone arcade and pinball games, along with guest speakers brought in for lectures, more contests/door prizes were included, an extra day was added to the shows, miscellaneous entertainment machines have since been brought in (such as slot machines, music videos, concerts and movie screenings were ran, many vendors have also been added along the years and kickoff parties have been held elsewhere before an expo.
Starting with the November, 2008 show, home gaming consoles were added to the lineup. The Vectrex has been present at several expos since, including the 2019 show.
