I voted for the Padific War Bunker because of a couple of reasons.
It really gave me chills thinking of someone actually building a diorama of a place they'd seen with the help of one who was there when it happened. That in itself is a rare and wonderful experience that I've never seen or heard about before.
Second; I see dioramas of german bunkers and fortifications all the time. This is the first time I've seen a fortification/bnunker used by the Japanese in WWII. They are so rare to see.
Aside from that, there were two other features I was happy about.
I loved the peek into the Forums. As fightinjoe said, it felt good seeing familiar names, as well as seeing some posts I may have missed from people whose posts I love to read. I'd like to see that expanded a little.
I also enjoyed the expanded reviews as well. Even though I like looking at some of the new things coming out that are in larger scales and glance through those reviews, I mostly read only the reviews of kits in the scale that I keep to. With more reviews, there is a greater chance of seeing a review on a kit in 'my' scale that I might want to go get. Thanks FSM for listening to us.
