Lego is too big to ruin, or has been so far. While it may seem like the once great company has been reduced to an action figure line, what with all the licensed shit and the "easy assembly" stuff, and "blind pack minifigures" being pretty much the antithesis of Lego, IMHO, but really they still also make, in addition to that, a ton of other really cool stuff. Stuff that isn't slathered in Hollywood comic book bullshit and let's you make your own stories.
Gundam is the same way. There are soooooooo many products coming out every week, many of them very cheap or dumb, but the good stuff is always coming too.
Btw, those Lego magazines really were awesome. So many great ideas. Nothing in them came from a set though so those set collector guys would probably need to up their dosage for a month if they ever saw one.
