That's a valid point but even if the entire scope was just to preserve every arcade game from 1970-1999, that goal could never be reached. We will never have them all dumped. Some of the games have had every copy destroyed already with no records proving it to us (so their chapter could be effectively closed) and some games will and are having their death hoarded in a Japanese closet. No need to even mention bugs. The goals are all not reachable until you bring them down to lower levels like "preserving all neogeo games".
