I've got mixed feelings about this line. From the start I've never been impressed with the value for the price point, even when they were the micro-machines die cast line. Some of the sculpts are pretty nice.....for example I like the new Nu-Class Republic Assault Shuttle.....I'm thinking abou picking one of those up. I like the fact that they put out vehicles we otherwise would not get (Twilight, Nu Shuttle, Neimoidian Shuttle, AT-OT (?), etc). The new jedi starfighters with huge triple hyperspace engines from ROTS are bulky and neat. But all the repaints start to drag me down....if it weren't for websites pointing out the new releases, I wouldn't even know some of them were new.
As for plastic....I'm also disappointed with the amount of plastic they use. As Hasbro has pointed out in various Q&As....they learned the heard way that there is only so much you can do with die-cast, especially in that small size. That's why some are mostly plastic. I'm cool with that, but they should have dropped the die-cast pretense and lowered the price too.
Latest word is that Hasbro is shelving this line after this year. I'm happy about that. Less repaints on the pegs, and an opportunity for me to pick up the ones I like....hopefully on clearance. And with the line cancelled, that give the opportunity to try and get a complete set one day.
