It would be cool to see how many hours I’ve spent in GZDoom, for example.
This is already in the database, there just needs to be an interface for it. Try this:
sqlite3 ~/.local/share/lutris/pga.db 'select sum(playtime) from games where runner = "zdoom";'
That should give you the number of hours.
That’s pretty cool. It says 11.9380555555556. Is that hours? Seems a bit low.
