"10. Gamers shall have the right to sell or transfer the ownership of a physical copy of a game they own to another person."

This is insufficient. It does not allow for the sale or transfer of games that have no concrete and separable instantiation.

Even in these times I can buy a game, download it, and play it, all without ever receiving a disc or box.

I do, however, receive an invoice, which represents my ownership of - but is not a copy of - the game.

Under law (mine; your mileage may vary according to state or nation) I have the right of resale. But due to the maker's implementation (no box and/or game tied to my account) no means to execute that right.

I suggest:

"10. Gamers shall have the right to sell or transfer their right to a game to another person, for no more than they paid. Where a game is tied to a player's account, the account system shall provide a reliable mechanism for transfer."

The phrase "for no more than they paid" is towards preventing MMO-style account farming. Its merit may be debatable.

The phrase "reliable mechanism" is towards preventing "but I emailed Acme Support to send you the game!" scenarios.

Noblesse oblige.
