It really depends, in some regions a preload is just nice to have, if you really want to play on release day. However in some rural areas all around the world, the pre-load is really worthwhile, since you do not need to spend ten hours downloading it on release day.
Before Amazon, Steam etc. it was quite normal not to play on release date, we just got used to getting everything delivered by the time it unlocks.
Back in the stone age people pre-ordered then made a midnight run to the local game store to pick it up on launch day, or they pre-ordered and hoped that the UPS dropped it off early so they could play before the official launch. The tales of rage and woe from those whose game didn't arrive on launch day or whose local game store somehow ran out of pre-order copies were epic.
