Heroic is a great option, and will likely remain most people’s preferred way to play Epic games on Linux/SteamOS. After all, a lot of windows users prefer heroic there as well due to the bloat/slowness of the official Epic launcher.

That said, official support is always good. It both represents that Linux is growing and a viable alternative to windows, guarantees better support from games on the platform in the future, and pressures other companies to also support Linux.

Basically this (and GoG adding support) are big deals, even if it’s not because we really needed their official support to have a good way to play their games.
