Basically they could split up the games content and sell them episodicly. For example, say it's a FPS game with 12 levels in the SP, the developer could split up the first 3 levels of the game and offer it for $10, and continue to charge $10 for every 3 levels, tallying the price to $40 for the entire SP campaign, then they could offer the MP part of the game digitally for $30. I think this could be a successful practice considering that ALOT of sales are lost to used games simply because people don't have $60 to fork out everytime, so why not allow them to buy the game in fragments? 

Thread blew up.

If it is digital only, then no way am I ever buying that.

Why not?

Yeah, I think it could really help because people who are on the fences about a game, will simply buy it use or wait till it's $20 anyways, so in the end the dev benefits. 

Make better games by not rushing it unto shelves (you will benefit in the long run by having steady sales).
And I think you also need to have an incentive to buy other games from the same Publisher by having like a reward/discount system. This can be done easily for digital games.

Because I never buy digital. Even for albums I still buy CDs, because I hate not having a physical copy for things.

CAPCOM would be all over that.

Let's take Call of Duty as an example, it's is the biggest after all.

Download only there are episodic releases, $10 for each campaign part split into 3 or 4? $30 for just multiplayer and maybe $30 for only Zombies.

If you want all 3, then $90 is well out of order. Many people only play multiplayer, in the case of CoD most people might just download mulitplayer only and save $30 from retail, which means developer makes less money.

If they were going to do it, they'd have to do a $60 retail version as well but because most people only play multiplayer, they'd still make less.

And it has to be a bloody good main story games for me to buy anything digitally in parts which cost more than a retail game. I ain't a fool and neither are most other gamers.

In theory it's good but customers are a fickle bunch...
