• Chat bubbles
• Overhead emote blocks [SWG]
---------------------------------
• MxO walking and sitting "moods" - probably the most character defining aspect I've ever seen added to MMOs for Roleplayers that actually changed your characters sitting posture and body movements when walking
• crossarms emote (held permanently until changed)
• leaning against walls emote (permanent until changed)
• kneel emote (permanent until changed)

The first two are separated from the rest, as they keep the roleplayers engaged in looking at the characters instead of a chatbox and are therefore given priority.
