There are some video game companies that put out games every 2-3 years, keeping their names on the map at all times. Other companies do so by releasing huge games only every several years, with big names like Rockstar Games and Bethesda being the ones most may think of. Blizzard falls into this latter category as well, especially given how Diablo 4 is still in development after Diablo 3 released all the way back in 2012.
