The new CCR topper is interactive and interesting.
Even though all SIC users have Goat Mania now, the JP topper is still cool. For those who don't know, if you don't have the topper (but do have SIC), then you get to Goat Mania with a super supply drop or something. But if you do have the topper, then the letters track your progress toward the topper, and it carries over from game to game. Each paddock progresses you one letter (or something).
And AIQ also has a topper mode with a randomized name, I don't know the full story there.
There have been a lot of good toppers recently
For instance:
Black Knight: Sword of Rage
JJP Pirates of the Caribbean pirate ship in a bottle looks cool, I'd have to see it in person
TMNT
Stranger Things
Halloween
