I did a bunch of these in the old days, even Battlestars, Moneymaze, Press Your Luck (which I did as Second Chance), and tons of others. But the #1 thing for several of them when I got done was....why?? As said earlier, almost all are doable, but when it gets right down to it, will anyone else play them with you?
I have a very workable BULLSEYE that has three snap-on spinners attached to the main game board, one in each swirled "window", with an outer ring of categories and values. I used the JOKER slot in the box idea for the bonus game. I have a LINGO that plays well with a dry erase board and master game book. As far as Love Connection goes, I have a version where couples race around a board with spaces requiring them to play various stunts like Newlywed Game, Scruples, multiple choice and similar quizzes where when they match, they "connect" and score a point, the first couple to ten points wins. I've kept only a handful of home mades, ones that have enough general interest. I'll put a few old favorites back together when time allows, but I won't go back to making one of almost everything again.
