I was thinking of possibly using a system similar to what I've seen on other servers for new players/characters. To be admitted to the world, the player must pass an entrance exam to prove he or she has read and understands the rules - that way, if the player breaks a rule, the excuse "I didn't know" isn't an option. What I was thinking would be to have an almost school-type room where there is an NPC at a desk. The player will speak to this NPC and the NPC will show all the server rules. The player will be given three options:
"Take the entrance exam": The NPC will then give the player a short quiz, and if the player answers all the questions correctly, they will be warped to the main city/town. However, if the player answers incorrectly, they must stay in the classroom to "study more" until they successfully complete the quiz.
"Screw the rules": The NPC will reply with "Well screw you too!" and either kill the player or close the player's client [I thought the client closing would be funnier].
"Never mind": The NPC will ask the player to come back when they're ready and the dialog will close.
Any thoughts or feedback is appreciated ^^
