Re: How to tie Humble Bundle 7 purchases to steam?
The developers of these games haven't yet uploaded the Linux binaries onto Steam. They will eventually. My advice would be to email them and politely ask when the binaries will be uploaded.
And yes, if you want to track the games through Steam, you would have to install them via Steam. It's not really all that bad to uninstall through USC and then reinstall through Steam.
Add me as a friend. Kill zombies/aliens/nazis with me. ON LINUX.
