When a game is single player only it is highly unlikely that customers want to accept this restriction. Of course steam is using the same way, but there you can at least easyly buy and download the games. But when you have the game on media thats really no good idea. For games with optional online it would be enough when you have to use that login/pass thing when you want to use maybe worldwide stats, multiplayer games via internet and similar things - but keep the single player part without. If the online part really gives extra value to the game then you don't have to fear pirates.
