Pong and Breakout were winning formulae for Atari, so it makes perfect sense they would want to try and do everything possible with this style of game over the years.
Warlords was one of the more interesting experiments, adding a healthy dose of theme, four-player competitive (or team-based) action and a couple of interesting additional mechanics.
It’s even reasonably fun by yourself… but get three friends together and you can expect the trash talk to flow freely within moments of starting!
