ZenGM Blog

Trade value is a tricky topic, and draft picks are a big part of that.

The big news is that, building on top of some initial performance improvements released last week, now all of the ZenGM games run about twice as fast.

Previously, all the awards in ZenGM were hardcoded.

The latest update to Basketball GM contains a new set of default injuries.

In my previous blog post about the 3-2-1 lottery, I wrote about how the probabilities for each pick change depending on how many teams trigger the top-1/top-5 constraints: [The probabilities] depend on how many teams in the lottery have constraints on win…

Back when I started working on the web-based version of Basketball GM in 2012, web development was very different. npm was brand new and hardly anyone used it.

Since the NBA has released the final details of their new lottery system (AKA the "3-2-1 lottery"), I have added it to BBGM.

If you create a new real players league in BBGM, you will now see expansion teams in Seattle and Las Vegas before the 2029 season, since that is what is now planned to happen in real life.

You make some trades, clear some cap space, and then when you get to free agency, there he is!

The offensive line stats recently added to FBGM have been very popular.

Okay this is like 3 updates in a row about FBGM awards which is kind of silly, but I think things are improving at least!

Adding an OPOY award to FBGM is a commonly requested feature.

Offensive line (OL) is an interesting position in football because it's extremely important but there are no traditioanl stats for OLs.

When viewing a live sim of a game (or when viewing a box score with a scoring summary, so in all the sports besides basketball) you will now see total values of key stats shown.

Tanking has been a big issue in the basketball world for many years, and it's probably never been more prominent than right now.

Lately I've been working on a bunch of little improvements for FBGM and I'm releasing them all today, since there are no real football games today so maybe you are looking for something else to do :) The new features fall into a few different categories:…

This is a niche feature so probably not of interest to most people, but it needs a blog post to explain!

Every year I post some usage stats here.

(This is an updated version of a prior blog post, but you don't need to read that old one, this is self contained!)

ZenGM now has a schedule editor!

As I sometimes do, this post is just me geeking out over some technical detail of the ZenGM codebase that doesn't directly impact gameplay.

The latest update to Basketball GM adds a couple new settings that enable some new ways to play historical real players leagues: Force Retire Real Players and Force Historical Rosters.

When creating a new Random Players or Custom league, there is a little "Customize" button next to the team selector that brings you to the Customize Teams page.

For a long time, the trade AI has been hardcoded to never trade away more than 2 picks in a single trade.

I just added 20 new teams to all the ZenGM games.

I recently realized that there are 4 people who have all the achievements in Basketball GM on insane difficulty.

Today I added a new feature to Basketball GM called "Import Real Players".

In real life, the draft lottery happens in the middle of the playoffs.

The latest update has two nice improvements to the cartoon player faces.

This started because of a post on Reddit wondering why ZenGM Hockey was slower than the other games.

BBGM has had real players and historical stats for a long time now.

On player profile pages, you can now view career totals/averages for ranges of seasons.

New UI feature!

The trading block is one of the most commonly used features in BBGM, and one of the most common feature requests for the trading block is to add some way to filter trades.

Every year I post some usage stats here.

I've been working on some stuff, but it's not done yet.

Dean Oliver is possibly the most famous basketball analytics guy.

The four factors are stats created by Dean Oliver to give some insight into a box score.

Until this update, ZenGM Baseball did not track blown saves (BS) or holds (HLD).

This is yet another blog post to explain a minor new feature!

Team Notes is a small new feature.

I've been working on this new feature for the past few weeks and I'm really excited to announce it because it feels like more than just one new feature.

This is a small change that you probably won't notice, and in a lot of seasons it won't even do anything.

This is a small feature, but it gets a blog post because it needs a little explanation.

The latest update adds two new features to the Free Agents page.

In the NHL, there are no ties.

Recently someone posted on Reddit about how he completed all the achievements in Basketball GM.

Having some convenient way to compare players is a very common feature request.

Every year I post some traffic stats here.

Merry Christmas!
