What rules do other people use when they catalouge their collections?

It all seems really technical :-S Plushies count but mighty muggs don't?

That's what the majority voted for.

Only licensed items count too?

Yep. Because otherwise the product simply isn't part of the Transformers brand.

No pre transformers or go bots, even though the go bots where officially taken into the TF world as an alternate universe.

Yes, and the Go-Bots who are produced and marketed by HasTak as part of the Transformers universe do count as Transformers (e.g. BotCon Bug Bite, eHobby Gobots, Fracture etc.) Even canonically the GoBots didn't become part of the Transformers universe until after Classics Megatron had inadvertantly caused the destruction of the Gobot universe and some of the Gobots had fled to the Transformers' universe as interdimensional refugees, integrating themselves into Cybertronian society.

Also, if you're going to let people count non-TF toys that have been integrated into Transformers like Gobots and let them count the Tonka Gobots, then a similar argument could be made for other such toys, like Star Wars, Marvel heroes, G.I. Joe, Garibo, Disney, iPod, Nike, USBs, Bathing Ape, Pepsi and other franchises that have crossed over with Transformers at one stage or another. So people could use the same rationale to include their Kenner Star Wars toys, Toy Biz Marvel toys, G.I. Joe toys et al. as part of their "Transformers" collection.

Personally I feel as long as it transformers (and isnt a drone), licensed or not it counts, with the exception of cheap KO's.

If that's how you want to personally count it then go for it. But for the purposes of the UCM anything not officially part of the Transformers Brand doesn't count. And remember that UCM rules cannot be changed otherwise the results from previous surveys becomes incomparable, which defeats the core purpose of the UCM in the first place. The UCM isn't saying "This is the best way to count," because there's no such thing as a "best" way to count toys. It's simply, "This is a way to count if you want to compare collection sizes and conduct comparative surveys." Outside of this context it doesn't matter how you want to count your toys; count however you want.
