Final answer:
Valve publishes Team Fortress 2, Half-Life: Alyx, and Portal 2, while Electronic Arts is the publisher for the Need for Speed series. The game 'Command' needs more context for a definitive publisher, but the Command & Conquer series is typically published by EA.
Step-by-step explanation:
The current publisher for the video games mentioned are as follows:
- Valve is the publisher and developer for games such as Team Fortress 2, Half-Life: Alyx, and Portal 2.
- Electronic Arts (EA) is the publisher for the Need for Speed series.
- The word Command could refer to multiple games, and without additional context, it's difficult to determine the specific game in question. However, many of the Command & Conquer titles were published by Electronic Arts (EA).
It is important to note that Valve is also the owner of the Steam platform, and although it publishes games for its platform, not all games on Steam are published by Valve. Conversely, EA has its own platform, Origin, where it distributes many of its games alongside other platforms.
