Glad you asked. I will be playing fully through the ones I want to afterward. So, I will be playing through your game to it's full length. Also, if it's visibly near the end when those 5 minutes are up I will just finish it!
Yeah, I think I'll just film the full playthroughs rather than live stream 'em. 5 minutes is enough to cretique a lot about any game. After that there is bound to be a lot of stuff, but it's less important than the starting impression.
