I want to nominate wgeurts for
The first, hopefully rather obvious reason is that it is a pokemon game. He plays pokemon on a competitive level and it's a big part of who he is. I think this part is fairly self-evident?
Secondly, we regularly see a wgeurts thread rating songs. He obviously isn't the only one doing it, but we see him in the song contest from time to time too. I'd like to think platinum is a rather nice play on how albums/songs can earn platinum when they're good?
Lastly, platinum is a unique, precious metal. I think it describes wgeurts well in terms of personality, but also in his unique creativity when it comes to designing mafia games (I believe he won a scummy for that too?) and in all the work he has put in the wiki, which is also a thing very few people have done to that extent.
So yeah, I hope this rambling makes at least some sense.
