Re-playability means just that. Can you generate a character? There doesn't need to be build options included but players should be able to create basic characters. Likewise there should be a selection of monsters & treasures for the DM to use in creating new adventures. A few levels as a limit is just fine. Moldvay basic limited advancement to level 3 and there was material for tons of campaigning in just that box, all low level of course.
Most importantly, when players were ready to move on to higher levels, the info in the basic box didn't become junk.
The 4E redbox was the worst offender in all categories here. What rules it did come with weren't compatible with the material it was meant to lead to. One of the very first things in the Essentials books was a little note saying that if you had started with the redbox too bad, you will have to make a new character. You just paid $20.00 for nothing more than ad copy to get you to buy this-thanks sucker.
No matter if its newbies or veterans, those who purchase a starter set should get some kind of GAME for their money and not just a one-use pick a path adventure book.
Can't XP you now, but this is the point!
