Only a few games were teased during Google's press conference in March, but the one big standout was "DOOM Eternal."
It's the next major game in the classic "DOOM" first-person-shooter series, and it's particularly notable here because it's a pretty demanding game in terms of hardware. It's a series known for being tremendously fast, and its fans demand pixel-perfect control.
In so many words, it's a great test case for what Google is promising: lag-free video games over modern broadband connection speeds.
A ton more games were announced during a stream in June.
"DOOM Eternal" publisher Bethesda Softworks is providing a gaggle of titles for Stadia's launch later this year: "DOOM 2016," "Rage 2," "The Elder Scrolls Online," and "Wolfenstein: Youngblood."
"Assassin's Creed Odyssey" publisher Ubisoft is also on board, and is promising "Just Dance," "Tom Clancy's Ghost Recon Breakpoint," "Tom Clancy's The Division 2," "Trials Rising," and "The Crew 2."
Some other major standouts were revealed during the first Stadia stream: "Final Fantasy XV," "Destiny 2," and "Mortal Kombat 11," among others.
