Mortal Kombat 11 and Power Rangers: Battle for the Grid are both coming to Google Stadia, as announced by Google in the days before EA Play and E3 2019's many press conferences. Google held a livestream to discuss Stadia, including revealing the list of over 30 games that will be available for purchase the day the cloud-based game streaming service releases.
Mortal Kombat 11 and Battle for the Grid are notable entries on that list because both are fighting games. Latency issues are one of the largest problems that cloud gaming must overcome, so Stadia's ability to effectively run both games will be a huge test as to whether Google's new service is up for the challenge.
Granted, Stadia is also launching with a library that includes Doom, Doom Eternal, and several other fast-paced first-person shooters as well. However, many of these shooters are single-player. Mortal Kombat 11 and Battle for the Grid are online multiplayer-focused titles where the game needs to read multiple button inputs in rapid succession. Any latency issues will create unfair conditions. Google's decision to launch Stadia with both Mortal Kombat 11 and Battle for the Grid available on day one is a vote of confidence on the company's part.
