Problem: while many noble players advance in the open, some try to hide their strategies during all the contest. I think the latter is just rational (everybody wants to win!), but it has some strong anti-fun and anti-competition effects (I wholeheartedly agree with a related remark that @Agade put in his postmortem).
So maybe we could add some rational incentive to release early and keep the best results in the arena? For example, for each player, consider the whole evolution of their ranking and compute a bonus for being high in the leaderboard for longer periods of time. At the end of the contest this bonus could enter into the final score.
A few technical details should be decided (What exact formula for the bonus? When do we start the observation? from the Bronze League? What weight do we assign to this bonus at the end?..) But all this seems not too difficult, and IMHO the benefits outweigh the costs.
So what are the potential benefits? The game would be more open. More “real time” too. The bonus would also be a fair contribution to telling apart players who are often very close to each other in the raw score: the one who has been leading more of the time would be deemed the winner. Last but not least, it’d would be an innovative approach to scoring AI contests that attempts to measure a kind of real life (“real time”) efficiency.
What do you think?
