Okay, played it through and have some thoughts about the walkaround.
Well, Cronus started out funny, mainly in how pathetic and hopeless he is. He still is kinda funny, but his conversations with Mituna just makes my skin crawl, so I just hate him. He's pretty much a mockery of bad fanfics of Eridan, overemphasizing his desire for relationships, hipsterism and jackassery. With otherkinism (is that even a word) thrown in for some reason. The "nyeh" seals it, since he's never said that in canon, but some fans seem to insist it's his catchphrase.
Mituna, he's something else. I only have the vaguest idea of what he's saying. Not particularly comfortable since he seems to be mental disorders played for laughs, but the whole chan backgrounds for his text has me wondering if he's supposed to parody chans, and also assholes on the internet who try to justify their douchebaggery by claiming to have mental disorders. Which would make it slightly less worse. I'm kinda ambivalent to him.
Meulin, she's okay if you're okay with overly excited, gif spamming tumblr fan girls. I am, so I kinda like her. There are definitely worse pre-scratch trolls. She isn't all that interesting, though.
Kerloz, WELL ITS NOT LIKE I NEEDED SLEEP IN THE FIRST PLACE oh my god. So, yeah, creepy mime who worships Caliborn, mind controls people, bit off his own tongue and sowed his mouth shut, and wants Lord English to win, what's not to love? Also, judging by his convo with Gamzee, it seems that Gamzee got his god tier outfit from Kerloz, not by actually going god tier. That, plus him never showing any god tier wings, it seems that he may have never gone god tier in the first place. He's just dressed up as one. I'm going with that.
All of them, except for Kerloz, are pretty much just parodies of various parts of the internet, and about as shallow as that implies. Heck, I think there maybe fics that portray Gamzee in a way like Kerloz, so he's a parody too. A terrifying one.
Also, Mituna and Karkat! Get your moirails under control and not worshiping evil time demons. Please, someone stop the Makaras, I want to sleep at night and not have my dreams be filled with hellish honks.
All in all, the pre-scratch trolls are tolerable, and the walkaround was okay. Kinda hoping we can see what dreambubble John went off to soon, though.
