Newzoo market intelligence director Emmanuel Rosier said rivals like the Epic Games Store, GOG and Battle.net pose no real threat to Steam's PC gaming dominance. He noted that major publishers such as EA and Ubisoft returned to Steam after building their own platforms, and that players' libraries and social graphs make migration hard.
