The show is partially to blame for why the toyline was so disjointed. Characters got killed off before their toys ever hit shelves, the show was so poorly run that they couldn't implement beast hunters properly, and so much effort went into the First Edition figures that really should have just been put back into the actual main line since with only one or two exceptions, the First Editions are far superior to the PRID counterpart figures - this is in part also to blame on the show because Cliffjumper's FE is a great figure and he's got a collective full season presence of less than one full episode! It also should be noted that some of the line's best figures were of characters who never appeared in the show. You'd be hard pressed to believe that Knock Out's toy and PRID Rumble were valued the exact same, since the former is extremely light and hollow, while the latter is a well designed little package that is only hollow in the areas necessary to hide robot parts in vehicle mode. They didn't decide RID was better, because RID was an emergency thing they literally threw together to keep Transformers at retail after the failure of Prime. You're completely overlooking the economic situation of the time period. Gas/oil prices were surging around the end of the 2000s and combined with even the loss-leader retailers having to raise prices to be more in line with MSRP, Hasbro in turn had to cut costs in production to be economically efficient as well. Oh, no, Prime's toyline didn't do well at ALL.
