Lord of Altera
Very anime (Glowing rainbow hair and eyes? Forlorn did it right in giving this stuff to the people who did things wrong/right in different ways, it ended up being only three people to get them. You don't hand that stuff out to everyone. I had to just keep my character standing back and out of the way standing there like an idiot because I didn't want his first roleplay to ruin him with rainbow hair. Yeah, I know it's a single strand and it could probably be cut off, but if you're going to add a 'this effects people, it's a dangerous space thing', make it something like a weird bruise or something under the clothes.)
There’s no reason to not engage because of the hair effect- as you said, it can be cut off. Your character wouldn’t be ruined by it. Also, the glowing eyes and such were temporary, like many other effects.
Very chaotic (DMs everywhere, the event area was an open mansion with a clear purpose at the end of it, but everything between the start and whatever the end was felt like forced filler, DMs given confetti to toss at you before the real show begins. I get it, context of 'creatures are being weird', but everyone was all over the place and I felt like it could be done better.)
Lack of descriptive writing and abundance of immersion breaking commentary.
Just shutting off magic. Sorry, mages! No exploding the event creatures. Or destroying the crystals. Yeah, I know they could be destroyed without magic, and I know the crystals themselves didn't shut off magic, but taking magic away still seems like a "go at our pace" move done wrong.
Take some time to actually write up meaningful dialogue, ambient descriptions, and heavily enforce not straying from that pack. DMs should keep their OOC commentary to a minimum unless absolutely necessary. Pre-write. There were tons of typos and empty descriptions of things and objects and places. Boring word choice. Write things up that sound write, descriptions to paste into chat when players reach a certain point. Sure I know things change on the fly sometimes but it's not as drastic as you might think. The event would go one way, the way the DMs intend it to, despite player interaction, if they truly want it to. I think they should. Improve your writing and people will enjoy it ten fold.
K I’m tired now
