Following! My daughter and I did a very rough playfield sketch/rules ideas of what we'd want in a Scooby Doo pin earlier this year and it was a blast. Mystery Machine flying out of the back panel, super stacked sandwich bash toy, Meddling Kids Multiball after you capture enough villains...it was a ton of fun, but we don't have any of the acumen to make a homebrew. But, if you ever want some people overflowing with ideas (I'm sure we all are here, to be honest), we're available.
