Hey Michael,
I want that choice too. I'm playing Half-life1 (CS) and Half-life2 under Windows. I never tried to install it with wine because wineapps are sometimes not easy to install. Thanks for you package - it works nice :)like i said before, the purpose of the package is to help the average user to easily run the software of their choice on linux. steam does include a store, but it is by no means the only purpose for the software.
I hope it comes in Debian. Best Regards, Max
