I do a first person video game let's play livestream show with level design / environment art commentary called Level With Me, and I've just finished playing through Half-Life 1.
I started with Half-Life 1 because it's a game I know pretty well, so I thought it would be a good first choice while I figure out how to do all this streaming malarkey. I'm still learning a lot about how to play / pace / perform, but I hope it's been entertaining and educational to watch nonetheless.
I've collected all 14 episodes into a playlist for your convenience. Each episode is usually less than an hour long. Also, you can "like and subscribe" the channel, and/or hangout during the live broadcast on Twitch every Tuesday usually from 6-7pm EST (GMT-5).
I haven't decided what the next game will be. If you have any strong opinions, please leave a comment. See you next week!
