With 60USD games being "the norm" these days, a lot of the games tend to not be worth the price that these greedy publishers are asking for. Let's look at some of the recent titles that came out:
Mass Effect 3 -- focused on single player with incentives on replay value due to outcome of characters being based on your past decisions.
Skyrim -- focused on single player, with replay value stemming from modifications and character rerolls.
Modern Warfare 3 -- focused on single and multi-player, with majority of replay value being on multi-player and future add-ons
Battlefield 3 -- focused on single and multi-player, with majority of replay value being on multi-player and future add-ons
Depending on the type of player you are, you can either be one of the first bunches of people who buy the game as it comes out or you can be the ones who wait 'till all of the add-ons and DRC (downloadable rip-off content) are collected into a "game of the year" package. As I am a multi-player gamer associated with a clan, I ended up being one of the first bunches who snagged Battlefield 3 early. I guess you could say that I'm sorta obligated (to myself) to snag a game early, despite the initial price offering. But when I view single-player games... like Mass Effect 3, Skyrim, or any other big single-player games out there, I think the price should not be tagged at $60 a pop, especially if the publisher and developer already has plans on delivering future contents. These days the term "DLC" is so blurred and screwed up that I often see it as an excuse for them to sell an incomplete game. I personally do not want an incomplete game. "Zero-day DLC" only implies that the game was incomplete to start with. And they should not be charging US$60 a pop for an incomplete game.
In the multi-player realm, things can be different... MMO and multi-player FPS tend to have people who will snag the game on the first day, since they're more than likely are either fans or are with clans/guilds that want to start as soon as possible. Prices on these can be set high (or low). Still, $60 is pricey as it is.
If I'm going to play a single-player game, I'd rather skip the initial price offering and wait it out. I already have tagged Batman Arkham City and Saints Row The Third as games that I will get later on and hopefully be collected into a Game of the Year package. You can't beat gettin' a good game at a fraction of its original release price.
