I really like the art over mirror blades on Funhouse. Thought about getting those once or twice but never pulled the trigger.
I added mirrors to my CV when i first got it, which i like. Recently added the official stern blades to Elvira and those were a piece of cake to install. For me it depends on the title and whether or not i think i’m keeping the game. Mostly i leave them bare as i don’t really notice them when i’m playing.
