Link to source repository under game info for FOSS games?

I just saw an open source game that was greenlighted -- Evolution RTS -- but there's no mention of the license it's under, or where to find the source code. Some gamers may be interested to have a link to the code repository for FOSS games; this could help further the development of open source games, which in turn improves the selection of quality games on Steam. With many games using languages such as Lua and Python for scripting, the barrier to entry is very low for interested gamers to submit improvements and fixes. Maybe just an added field for the license under game info that when clicked on, takes you to the repo?
