Most of the boxed Armada toys aren't that fun to play with. Their articulation is often hindered by being loaded with gimmicks. Superpants Prime is a block... nearly as bricky as Powermaster Optimus Prime, which by 2003 standards is atrocious. The automatic transforming trailer gimmick gets old quick. (-_-) Some of the Deluxes are okay (but not astounding). I actually find the most interesting toys from Armada were the Mini-Cons! :) They're like Micromasters but with better more contemporary engineering.
I think it's best to check out someone else's Armada toys before deciding on whether or not you want to collect them yourself. Try before you buy as they say. :)
