Yes, I agree. I think that if DiD "did" a WWI line, it would sell like wildfire. DiD Would no doubt make great figures, and what have they got to lose? WWI would bring in a ton of money and a ton of joy to 1/6 collectors around the world. My only concern, though, is that 1.) DiD makes terrible American headsculpts, 2.) They make difficult to deal with hands, and 3.) Their equipment is very easily broken. Seriously, a baby could break the accessories that they include with their figures. I don't know why, but it seems that DiD makes cheap equipment. It looks very detailed and expensive - but the quality is the exact opposite. \
I would have to say that DiD needs to make some changes before considering a WWI line. I do not want to spend a ton of cash (Because a DiD WWI figure is bound to be worth BIG BUCKS!) on a WWI figure and break it by just trying to put the gear ON the figure.
But Yes, I do want to see a WWI line from DiD. Bottom line message to DiD
