Wow, I literally just thought of that place like 20 minutes ago!
Here's what I've heard through the grapevine about that place (keeping the source of this info removed).
1) They removed their mediocre outdoor mini golf course and made it indoors in a room and it's now as much fun as mini golf on your living room carpet, hitting off of scattered books into a solo cup.
2) Their pinballs have decreased in number (purely based on this person's memory of what he recalls from ~5 years ago).
3) (From another source) Their pinballs don't appear to get regularly serviced, so you don't know if you're playing a malfunctioning game until it's too late.
Again, all word of mouth, but this is what I've heard over the last few weeks. It's a bummer because this morning I was thinking of taking my son camping up in that area and thought of making the trek over to Funspot to see what it's become. I personally haven't been there in 10 years.
