I am not sure why people feel that a new player should have the same advantages as an older player, or should even catch up to the score of an older player. The Metaverse, in my opinion, is about two things. One, a record of your scores as an individual, and therefore each game should reflect the score from the game, i.e., raw score. Two, a team competition where each player contibutes to the overall score of the team. The team score can be arranged in any manor one wants, based on the raw scores of the team members. I am not to concerned about the team scores or how they would be calculated.
But, for individual scores, one would have a list of the highest scores in the game, for however many categories of game play one wants to track, for example, highest score for each dificulty on each size of galaxy. This would be a lot of categories, but also if someone wanted to be tops in all of them they would really have to play many different styles of games. New players have as much opportunity to compete in those categories as anyone else. Of coures, their experience would probably indicate that there scores would not be very high on their early games, but that is the nature of the game.
