I would pick the Hall of Justice or the Watchtower.

As cool as a BAP would be I just can't see it working well without a single BAP taking an entire year's worth of figures to do it right. Look at the Charmed BAPs done by SOTA... those are incredibly detailed but still very small in comparison to what a Batcave or Watchtower should be... Even the fantastic Buffy Library is still too small in comparison to what it would take to truly do something like the Batcave justice. The $10 price point would limit a BAP so severely... I have no problem with including some set pieces the way Hasbro has been doing with Star Wars the past few years but, personally, I think it would be much cooler to get a wave a year that had "companion" figures in place of the BAF. Characters like Mxy, Bat-Mite, Krypto, the Guardians of Oa, L-Ron, Oberon and so on...

yeah I can agree with some of that. What if the BAP is more like Batman coming with the Batsignal, or Superman coming with the Bottled City of Kandor? That might be cool...

Superman - Kandor, Phantom Zone Projector
Batman - Batsignal, Bat Phone, Robin costume showcase
Flash - Cosmic Treadmill

What else?

The Batcave ! Or just a awesome Bat-computer ...

Sounds like the JLA museum pieces that DCD is putting out...

yeah I thought the same thing. But these would be scaled for the 6" figures vs full-size props.

A "JLA Trophy Room" theme would be cool, like each figure comes with a scaled piece - Despero chess set, Starro in showcase, Green Arrow's trick arrows...

Kirby's Dots.
Hourman's time ship
IF
...

Yeah, exactly like the JLA showroom! Or Batman Beyond's batcave, with all the defeated villain propaganda...the Gray Ghost costume.

It'd be cool to see the different kryptonite rocks, meta helmets, a starro, the chess board to Despero, weapons wall, etc. Maybe even the classic Superman cape from Superman #75.

If they do playsets, do them separately. They did that with the 2002 He-Man's Castle Grayskull.

I wonder if the new bases for '09 will start to fill this request...

The base packed with the "anchor" character (if that's what you're refering to...) is supposed to be the same base as the ones sold at MattyCollector except they'll have the character's name printed on each one.

yeah, that's the base I was referring to. You could be right. I'll ask Mattel and see what they say...

1. Titans Tower
2. JLA Satellite
3. JLI NY Embassy

Tho, if you are just talking a background from inside one of those places, then they should be a Stand/Background.

The DCU Classics stands they sell suck anyways.

Do what Playmates did with Star Trek. Make a bare bones playset and include set pieces with each figure so you can complete it.

Batcave Playset: Retool the large Batman Forever Batcave and make minor changes to up the scale. The three main bases would be fine, but the batcomputer, elevator, stairs and turntable need to redone or scrapped. A turntable for the large Batmobile might be too big. You would not need to retool the whole playst, just a few parts of it.

BAP: Included with a figure

Batcomputer(s): Could be smaller parts the snap together to make a larger display

Bat Gadgets Wall: Have most molded and painted on, but have open hooks to hang parts that come with other figures.

Trophy Case(s): A Robin suit case would be great, but other accessories used on prior villains could be put in display cases.

Bat Lab: Various lab equipment, microscopes and such.

would love a big play set, but it would work best with DCIH, Playsets in order of perfernece

1. Hall of justice
2. Legion of Doom Hall do not know what it is called
3. JLA Statilight
4. fortress of solitude
5. I guess the batcave

Hall of Doom

Yes, the Hall of Doom to go with all of the LOD members they've been making & the Hall of Justice would be very cool.
