 ## Game Updates
 
+### [A/B Street][abstreet]
+
+[A/B Street][abstreet] is a game by [dabreegster] exploring how small changes to
+road space and traffic signals affect the movement of drivers, cyclists,
+transit users, and pedestrians. The game models Seattle as accurately as
+possible using [OpenStreetMap] and other public datasets, lets the player adjust
+existing infrastructure, and then does a detailed comparison to see who the
+changes help and hurt.
+
+First of all, [a standalone 2D GUI crate][abstreet-gui-release] was published
+extracted from A/BStreet's GUI code.
+It features fully vectorized text using [lyon] and supports lots of
+widgets such as "buttons (with keybindings), checkboxes, sliders, pop-up menus,
+text entry, and some data viz things".
+Thanks to its simplicity (everything is a colored polygon), this crate runs on
+many different architectures and even on the web via [glow].
+
+Here's an example of what it can do:
+

+
+Dabreegster also uploaded a recorded version of their
+[rust meetup talk][abstreet-meetup-talk] about the inner working of abstreet.
+
+> In case anybody here is interested in more city simulation in Rust,
+> the talk is about half project overview and half deep dive into code.
+
+ABstreet had some great contributor work coming in, notably from omalaspinas who
+implemented an optional SEIR pandemic model into the game.
+
+And for anyone interested in more frequent updates, the
+[abstreet subreddit][abstreet-subreddit] has had weekly update posts since
+September 2019.

+### [Citybound]
+
+![citybound web ui screenshot](citybound.png)
+
+> Citybound is a city building game that uses microscopic models to vividly
+> simulate the organism of a city arising from the interactions of millions
+> of individuals.
+
+It is developed by [aeplay][aeplay] and uses a homemade actor system for
+everything called [kay], you can see its power on
+[this impressive tech demo][kay-tech-demo].
+
+In April, aeplay made two livestreams about conceptualizing pedestrians and
+pandemic models using feedback from the chat.
+You can watch the replay for the two livestreams on youtube: [here][cb-live-1]
+and [here][cb-live-2].

+### [Scale]
+
+![Pedestrians](scale.png)
+
+[Scale] is a granular society simulation by [Uriopass], with the objective
+of having fully autonomous agents interacting with their world in real time.
+
+A [devlog][scale-blog-post] was published, explaining how pedestrians were added
+to the simulation, and that a new renderer based on [wgpu-rs][wgpu-rs] is in
+development.
+[A short video][scale-pedestrian-video] was also posted together with the post
+for a more concise update.
