1. What do you think LEGO would never do that you’d love to see?
I always thought it would be cool if someone made a feature film based on a lego product line (read: but not KK2!). Not, you know, animated minifigs but an actual live action movie with lego factions, balck falcons, royal knights, etc.
2. What types of themes/concepts should LEGO stay away from?
As many mention above, things that have limited scope. Lego is meant to be backward compatible, everything made today should be able to integrate with everything made in the past 50 years. Stuff that is too focused and doesn't leave room for expansion, it could be pieces, colors, or entire themes, is useless and kills the imaginative drive. Storm trooper helmets can only ever really be used for storm troopers, for example.
3. Are there any community projects/products that you’d like to see turn into a LEGO set?
Like many have already said, modular stuff is something that is big in the community and would make some great product lines.
4. Are there any projects/products that we should stay away from?
Stop trying to use stuff in castle that is not castle. We keep seeing all these parts from bionicle, juniorized stuff, etc, that keeps showing up in castle sets that don't really have any place. Look at the King's Siege Tower versus the
original prototype: someone decided "hey, we've got this mold for this giant shield that is pretty much useless, can we slap it on something and make it look like it was intentional?"
If you mean *community* projects you should stay away from, I might point out that I still have yet to see what's so great about the "bonktrons."
5. What types of products/themes/concepts do you think are missing from the assortment over the years?
There's a difference between a lot of the best MOCs I see and official sets, and I want to say its that the MOCs are more "complete." MOC makers always seem to go that extra step to fill in cracks, stock up on accessories, figs, etc where official sets always seem to have a loose, disjointed feeling that was not so present back in the day.
Like others I'd like to see more historical type stuff, but there's room for fantasy too. IMHO KK2 was a decent idea just a poor execution. Nobody wants purple armor for their figs, but on the other hand we have the shadow knight helm which is awesome. I'm using shadow knight helms for about half my black knights now. Nobody likes KK2 swords, but I can see other fantasy sword designs that could catch on.
Speaking of KK2 though, we've got all these new shields and faction logos, why not do separate lines for some of the rainbow knights? I'd love to see a Santis faction with bear shields, banners, etc.
Its hard to think of any new themes, pretty much everything I thought could be done when I was a kid (arabian, medieval asia, etc) has been done now.
6. Are there things we’re missing in general? On box? In the instructions? In the box materials?
Hard for me to say, haven't bought a boxed set in a long time. I agree that having a lot of alternate building ideas was great back in the day, though, and it definitley seems to be lacking on the newer boxes I've seen.
