There's more concepts than that.

Ones I didn't like at the time:

Action/Vehicle Packs sucked., big backpacks that had wind up features and cost as much as a figure.

And any deluxe figures sucked in some way, because really, I wanted the figure not the gimmick.

Air Commandos, buying gaudy gliders to get new figures. $8 each

Battle Copters, had to buy a useless to get a figure, $8 IIRC

Super/Sonic Fighters. Most were repaints. $6 to $7 for a repaint and there were 8 different sounds but 12 figures.

Shadow Ninjas are awful. $5, I think.

Star Brigade Armor Tech was less articulated figures with gorilla proportions. $5.

Eco-Warriors, you know...$5 each

$5 isn't that much today. But remember figures like Big Ben were $3 U.S. at retail.

So would you rather buy 5 figures or 3 eco warriors? Or two Super Sonic Fighters?
