I've just finished up the latest version of
8BitMMO!
Biggest changes since S4:
- Lighting!
- Grief protection - now you can only pick up items that belong to you (or have no owner). You also can not build in the same tile as someone else.
- Roads - travel 2x as fast
- Signs - Press E to read. Type /sign <your message goes here> while next to a sign to set the message.
- Doors - Press E to open. Comes in two varieties, yellow handle doors that allow everyone entry, and red handled doors that only admit the owner.
- IRC integration - you can idle in irc.editingarchive.com #8bit and chat back and forth between players in-game
- Password reset via e-mail
- Right sidebar displays latest news & relevant links
- Facebook / twitter feeds set up
- Dirt is shown on the lowest z-level instead of empty space
- New, faster world renderer'
- Gold can be picked up and is now correctly added to money instead of going into inventory
- Server auto-restarts on crash / hang
- Lots of misc bug fixes & performance improvements
Known issues:
- Lighting doesn't recalculate when the world changes
- Signs in some tiles are hard to read (for now, just place in another tile next to it)
- In-world text (text shown over players & npcs) looks like butt.

Please give it a go and let me know your thoughts!
