Gday
Ive just recently migrated from win7 to Linux
I was shocked to see that Steam Linux + Wine is not integrated
to install DX9c games as an wrapper , just like dosbox supported titles

Why cant we right click on an DX9c game and choose INSTALL in WINE
instead of it just bitching its only designed for Win dx9c "invalid platform"

Steps for reproducing this issue:

1. Ubuntu Mate 17.04
2. Install DX9c game , eg Grim dawn
3. Invalid platform error instead of installing via WINE within steam linux native client
