Isn't DDR supposed to refer to a type of
RAM and
Dance Dance Revolution?
Don't you know that DDRs (Double-Decker Roads) can't be done since they'd have a fraction of the capacity as their unstacked version and that there are no more networks to work with?
Besides, don't you want to talk about optional third-party lot-based NAM accessories instead, like my
NWM Traffic Restriction Lots?
Who goes to SC4D Wiki, anyway...?
