I did a post about all the games I played in 2014. The only source of data I had was the total play-time from Steam, but I really wanted a way of getting more detailed information (like when I played them and how long for).
I thought about it and I what I wanted was script that would record the time processes that were running on my system and write them to a file. The script would stay running and update the file at periodic intervals to record how long the processes had been running for.
