Hello Jonny, Joel and Slicedl,

After watching “Secrets of Warden ” YouTube video I was wondering, does every single new Minecraft feature goes through so much prototyping, testing and balancing?

If yes, how many prototypes do developers draft for a new feature? Is it based on the feature? Does the team also keep in mind the community feedback you will be getting after releasing a feature in the form of a snapshot? 

Thank you for an amazing game, and a wonderful podcast!

Hi Sliced, Joel, and Jonny,

I was wondering how often feature ideas get discarded at Mojang because of how they would affect the framerate. I understand that you have to balance Minecraft  running on older hardware and giving the game as much immersion and depth as possible. 

I’d love to hear your thoughts and opinions on this. 

Chunks Away,

Hi Joel, Pix and Sliced,

Long time listener, and finally decided to support the show I’ve been listening to for so long.

For Sliced – I’d like to know how successful the split (of 1.18) has been in avoiding developer burnout. 

Being a developer in my past, I know how stressful outside pressures can be, and that there can sometimes be a lack of empathy for the work that goes into a development project. (Especially bug fixing.)

Do you think that Mojang having such a big following, and engagement with its community allowed you to do this without seeing the community backlash we have seen with other studios when either delaying release or shipping incomplete software?

Thanks to all of you for what you do!

PseudoVar died using experimental features.

Thank you to our Patrons!

A Dark Experiment

The First Look At The Deep Dark & The Warden With SlicedLime

SlicedLime talks about their history as a game developer, working at Mojang, as a content creator, and the sometimes struggle to find that work, life, Minecraft balance. Is there such a thing as too much Minecraft? The discussion is packed with even more Minercraft with Jonny, Joel and SlicedLime all discussing their first impression of The Deep Dark, The Warden, and the potential this new player experience has for the future of Minecraft.

Additional emails and questions for SlicedLime.

Hello Joel, Jonny, SlicedLime,

I would like to ask SlicedLime to describe what a Mojang Tech Lead for the Java game does. As a person working in software development myself, I have some rough idea, but others might not. Plus, these job titles mean something a little bit different from company to company. What are your most common tasks, and responsibilities? What kind of decisions are you making and do you still code at work, or is it mostly meetings and paperwork for you?

Thank you so much!

SUBJECT: Key Technical Challenges

Hello Joel, Jonny, SlicedLime,

What were a few key technical challenges with The Caves & Cliffs Update, Part 2 in terms of the changes to terrain? How did the team deal with these?

Did the (experimental) snapshot process help in gathering meaningful feedback from the community with regards to bugs and issues the team needed to look at? I feel like we saw a lot of community interaction from the devs as 1.18 was being developed. Was this useful to help shape the update? Will this be something that will continue in updates in the future?

Lastly, just a massive thank you to SlicedLime, all the devs and everyone who works on Minecraft. It’s amazing how a sandbox game in a blocky world can bring people and communities – Like this one! – together in the way it does!
