In fact for older consoles it was simpler than that.MKCL said:Not to be a dick, but we haven't been getting complete games for a while.
It used to be:
1) Purchase Game
2) Install Game
3) Enjoy Game (And maybe patch)
Then it became:
1) Purchase Game
2) Install Game
3) Patch Game with things that were fixed but weren't fixed in time for the discs.
4) Enjoy Game
5) Patch Game a month later.
(Just noticed the first three steps above are Pie. Cake can go F itself.)
*for teresed*
1) Buy Game
2) Insert Game into Console
3) Enjoy Game
Possibly with a 2a) Jiggle cart to make it work
