+[2:01:40][@jmc516][Q: Have you ever found yourself angry with something in the game? Maybe the progress or a certain part? If so, how did you get past it?]

+[2:03:21][@nickito97][Q: Do you ever feel like everything needs work to the point it's demotivating / you're not even sure where to start?]
+[2:05:28][@garryjohanson][Q: So we've been debating the merits of using a garbage-collected :language like go in a network situation where you have absolutely no prediction of what data loads will be coming in. Do you think a language like go would be a good choice? (I feel like you've answered a question like this, but I honestly don't remember your response)][:memory]
+[2:10:26][@tili_us][Q: Is it better to work on a fun task or a task that is more important if you have limited time?]
