These little adjustable panels that let you customize your character experience are really nice in our Rust based Ultima Online client. #RustUO

Procedural map generation is hard... no one has done it successfully in Ultima Online yet... but here we are with full procedurally generated maps, with biome support... proper coast lines etc... #RustUO #UltimaOnline

In today's wild updates - we took a stab at procedural map generation in Ultima Online. We now have a fully working procedural map generation tool that's web based. We'll be adding it to our website at some point soon for everyone to use. #RustUO #UltimaOnline

Dark nights... colored lights... it'll be so nice to have a client that enforces the visual immersion UO was meant to have... Making night sight useful again. Players always wanted a 'cheat free' and 'level playing field', our client will deliver that. UO with no Razor, no scripts... #UltimaOnline at it's finest, by #RustUO.

Okay... last one for the night... 5000 users online the load is small enough you could run it on a free tier AWS EC2 Instance. #UltimaOnline #RustUO

500 MB of RAM and 10% CPU. That's the entire footprint for 5,000 connected clients, with AI speech-model NPCs roaming the world, holding conversations, and executing skills. Sim load is at 40% with headroom to spare. All on a desktop computer. #UltimaOnline #RustUO
