The development rate of videogames has become insanely slow. This can't be attributed to them making more technically complex games as we're effectively past the era of regular mega-AAA blockbusters, something only a handful of studios do now. This can't be attributed to the coofdemic either, as it was something that started before that and was only exacerbated by it.
It explains why you see games released 10 years ago on sale for $30 when you used to see old games for only a couple dollars. They're no longer used to pull you into a series to get you to buy the newest titles.
To put it into perspective: Dragon Age: Dreadwolf currently has no release date. Dragon Age Inquisition is nearing a decade old, the time gap between DAO and DAI is nearly half the current timegap of DAI to ...nothing. This is the studio that was previously pumping out two major franchises simultaneously.
And it's most definitely not limited to Bioware, it's across the entire industry. It's taking developers 4-5 years to make games they used to make in 2.
Batman Arkham Asylum? 2009. Arkham City? 2011. Arkham Knight? 2015. 5 years later they announced the Suicide Squad game they're still working on with a planned release date in 2023. Rocksteady has released 0 titles since 2015 except some crappy VR shovelware game in 2016.
Firaxis: Civ 5, 2010 with a stupid amount of DLC. Nu-Xcom, 2012 with major expansion in 2013. Civ: Beyond Earth, 2014. Nu-Xcom 2 in 2016 with a major expansion in 2017. Civ 6, 2016, more stupid amounts of DLC. ... Nu-XCOM Chimera Squad, 2020. ... Marvel's Midnight Suns, later this year. delayed!
Harebrained Schemes: Shadowrun Returns, 2013. Dragonfall, 2014. Hong Kong, 2015. Battletech, 2018. Nothing since besides a recent poor console port of the Shadowrun games.
Bethesda: LOL
Techland: Call of Juarez Bound in Blood, 2009. Jaurez: The Cartel, 2011. Dead Island, 2011. Dead Island: Riptide, 2013. Juarez: Gunslinger, 2013. Dying Light, 2015 with an expansion in 2016. ....... Dying Light 2, 2022.
Are there some exceptions? Sure, but they're definitely in the minority, and I have a feeling a lot of them will end up being Japanese.
Gamedevs are relying heavily on profits from older games now, that's why you aren't getting your sales anymore. Also, remasters for everything!
