All good points above, but my contribution is this: I can always look at pictures of these figures (or any others) online if I'm feeling nostalgic. But the Classics line has impressed and inspired me to the point that I want to mix them with select pieces of vintage MOTU, as well as try my customizing skills with this line as my medium. For that, I gotta open 'em.
I'd strongly consider the above suggestions regarding select openings to see how it strikes you. Good luck!
