1. Do you feel experience requirements are acceptable in Large (Theme/Normal) games?
Yes, I guess so. Large games need to run smoothly for them to work.
2. If so, do you think they would be appropriate for other types of games, such as Mini Theme games?
No. It's good for less experienced players to get their experience in Mini Games, and playing in themes will help them enjoy the game and learn more about it - this couldn't be done if mods were putting experience limits on.
3. Should Mods be allowed to ban specific players from their games?
Yes.
4. If so, what reasons are acceptable for doing so?
I'd say players who have had to have been replaced in their games more than once, and players who have gone against the rules of previous games (Such as rules in Theme games).
