Game developers end up using the distro tooling when they port the game to SteamOS. One of the tensions with Ubuntu was that developers felt familiar with it (good) but the system libraries lagged what was needed by new games (bad) so developers would need to run their game in a SteamOS Ubuntu-esque chroot instead of their Ubuntu host system despite them being very similar. Arch does provide the promise of easier native porting because testing the game during active development (on an Arch host system) will be closer to the SteamOS Arch-esque system. It's small but meaningful for those who try to support SteamOS to the maximum extent, which is important when you're trying to seed a new ecosystem.
