I think Putting the date is exactly how you approach this, Unfinished: game pre-alpha 1.34 is quite unwieldy .Putting the date also allows you to easily come back to a game say 6 months later after some major patches and show how much has changed in that timeframe rather than between v.5 - v.8, and of course people who care could lookup the notes themselves for a detailed log. The concept of looking at Unfinished games is pretty cool idea especially how popular alot of these games are this last year.
So after a couple of days of using it, I can say it works really well. Youtube is the easiest way just press the chromecast button to send it over and it loads the best quality one. The other way is to cast your tab using the chrome extension and then play the video on your computer and full screen it. I'd say the delay is around 1 second, it sends the audio as well and mutes the audio on your computer. Overall its just so easy and works, I really like it. Not to put more work on the engineering and Alexis but maybe they could add a chromecast button to the video player in the future, not that its needed but it would simplify it even further.
