I'm planning to go soon to a round one and I'm slightly sensitive to flashing lights. Migraine and stuff, not sure about seizures not wanting to find out the hard way.
Are the machines really like fast flashing or is it average ? Also alot of videos it seemed kinda well lit inside? That makes any type of flashing more tolerable. I want to make sure it'll be safe for me to go.

My second question is about the honkai star rail collab.

Also does anyone think the HSR collab will last till June 15th ?? And on the recent post it said nationwide but before it was just two locations and I got confused if it'll be at more than those
