recently i have been asked this question from my friend witch i struggle to answer.
quick summary I'm working on a World war 2 game an FPS shooter with multiple map and historical events and weapons from that era.
i mention that to my friend and they asked me "why should we play your game? we already have many world war 2 games including Call of duty and battle field high quality with good budget what can you offer?" I struggle to answer this question and this is a valid point why play forza horizon while grand turismo exist(or the opposite) why should i play other City simulator while Simcity exist and so on.
and help is much appreciated.
