Tribal Trouble

Tribal Trouble is a fast paced realtime strategy game where your job is to lead your cartoonish and somewhat clueless kinsmen (be it Vikings or Natives) to new discoveries and victories as tribal clashes rage across tropical and northern islands.
Unlike most other RTS games, Tribal Trouble is quite easy to grasp and offers single player skirmish and campaign games as well as online multiplayer battles on a near infinite number of maps.
