I want to make some suggestions, I hope they reach Valve, although I think you already have plans for software, but who knows, maybe it will help!

It would be awesome if every Steam Machine and Steam Frame came with Half-Life 3 in the package! If the Half-Life rumors are true, that would be epic, explosive!

Other games could be announced for the future:

Left 4 Dead 3 (for Steam Frame/VR hardware as well)

Portal 3 (with GLADOS being a real AI, and with the same voice) (for Steam Frame/VR hardware as well)

Team Fortress 3 (for Steam Frame/VR hardware as well)

CS VR (a specific version of CS 2 for VR and Steam Frame)

DOTA 2 for VR

Remastering Half-Life 1 and Half-Life 2

Games from other companies as well, such as:

TitanFall 3

among others that Valve could promote!

It needs to be made explicit that the devices don't require a subscription to play online or save to the cloud!

And partner with EA and Ubisoft subscriptions, and anyone else who wants to offer subscriptions on the platform!

Regarding price:

Steam Machine: $400 to $500

Steam Frame: $500 to $600

Steam Controller: $50 to $60!

But it depends a lot on your costs, especially the Steam Frame! But I know you don't need to profit from the hardware or the retail hardware, which gives you hope!
