From Generation one till Today, What gimmicks and Extras have we now lost?

I can't help feeling that in gaining articulation over the years, we have lost the playsets, and extras we came to enjoy in Generation One toys..
Generation One extras lost, Hasbro will not produce in the future:
Prime's trailer
Megatron's extra attachements, nerf gun attachments would just be a slap in the face..
Ironhide's Trailer
Ratchet's Trailer
Giant transforming Bases
chrome coloring
workable diecast, frames and other parts that would add to the toy, instead when Hasbro did Titaniums, they went and did solid chunks, instead of just parts here and there..
Ball and chains and energon axes
Triple Changers ( with the exception of the "Animated prototype" I have yet to see a real triple changer, whose body actually is 3 different altmodes.. Cybertron Megatron doesn't count..
