I think “likes” applying to prestige is a great idea, but with a bit of a manipulation problem. We already see people get upset over prestige when people “optimize” their scores by spamming high value blocks with no consideration toward placement or function. Now imagine those same people pushing everybody they see to give their builds a “like” just to raise their score. Now imagine somebody who is truely famous, let’s say a famous youtube like Markiplier with tens of millions of subscribers, say he comes along and building a mud hut. Even if only .001% of his fans “like” his mud hut, that’s a massive amount of potential prestige gain. Imagine if Markiplier actually vote pandered.
I don’t like to shoot down a good idea without proposing a solution though. So, one possible way to allow “likes” to affect prestige score fairly without being massively susceptible to like manipulation would be to cap the number of “likes” that affect a build’s final prestige score based on its base score (score before bonuses and multipliers are added). So a build with a base score of 1000 may only allow the first 10 likes to apply to its final score, and a build with 100,000,000 base prestige allows for many more likes to apply to final prestige. This is still susceptible to “like” manipulation though, just much less severely.
Another possibility is to not quite integrate likes into final prestige at all, but still allow builds a rating based on “likes” and base prestige. Similar to the above solution, but rather than add the results to the final prestige score, you would rank the results on a letter scale. So, a popular build would have a score like 10000, and a letter score like A+ based on the number of likes. The letter score has no effect on final prestige score, but reflects the number of “likes” on a relative scale based on base prestige, not total “likes”. This makes it so two builds of similar prestige score can’t vote manipulate to get ahead of each other.
