forza ( ; italian for "power") is a series of semi-sim racing video games for xbox consoles and microsoft windows published by xbox game studios. the franchise is primarily divided into two series; the original forza motorsport series developed by american developer turn 10 studios, which focuses on primarily professional-style track racing events and series around various tracks both real and fictional, and the forza horizon series mainly developed by british developer playground games, which revolves around a fictional racing and music festival called the "horizon festival" and features open world environments set in fictional representations of real world areas in which players may freely roam and participate in racing events. each main installment of both series have so far been released on a biennial basis, with "motorsport" entries releasing in odd-numbered years and "horizon" entries releasing in even-numbered years. however, this pattern was altered due to the absence of a new "forza motorsport" game in 2019, with turn 10 creative director dan greenawalt having confirmed in june that there would not be an eighth "motorsport" title that year.
