"sanctioned" is the term they use to describe the relationship with us, I was just using their terminology, but yes users are allowed to use it to play on official servers.
You can load and get into game with Firefox, you can click the proceed anyway link at the bottom to try it, however performance is worse and some features don't work.
Namely Firefox is missing support for the `FileSystemFileHandle` locking mode which prevents multiple tabs from running (cannot share file handles), and they have a negative standards position on implementing some other parts of the File System Access API like `showDirectoryPicker()`.
I've been working on an WebAssembly Ultima Online browser client. It's a heavily modified port of https://github.com/ClassicUO/ClassicUO (an open-source UO client written in C#).
You can play the test version using Chrome, however beware as it needs to download over 2GB of game resources, and still has a few glitches with audio. That said it runs at a stable 60fps on most systems I've tested so far. We have two test servers, one in AU and EU. Auto-account creation is on so just type in a username/password to get started.
The server the client connects to is another project myself and a few others are working on. It's a ground-up rewrite of an early 2000s custom server for UO called Zuluhotel.
Something similar was done in the Left 4 Dead series with the AI Director:
Tim Larkin: We took several steps to keep the music interesting enough that the players would be inclined to keep it on as they play. We keep it changing so it won't become tedious; to this end, we created a music director that runs alongside the AI director, tracking the player's experience rather than their emotional state. We keep the music appropriate to each player's situation and highly personalized. The music engine in Left 4 Dead has a complete client-side, multi-track system per player that is completely unique to that player and can even be monitored by the spectators. Since some of the fun of Left 4 Dead is watching your friends when you're dead, we thought it was important to hear their personal soundtrack as well. This feature is unique to Left 4 Dead.
For single-player it works really well for building tension leading up to being attacked by waves of zombies and creating calm spots after high-stress encounters.
In the online versus mode however players got really good at using the musical hints as "tells" for when certain actions happen in the game. Most notably there were musical signatures consisting of a few notes that would play when the special infected characters spawn. Coordinated teams could use this to their advantage know when the infected team is about to stage an attack (like an ambush at a choke point in the map).
