I keep reading how it's so difficult or near-impossible to create characters without DDI because there is so much "crunch" to keep track of. Before DDI and 4e, that wasn't an option because very, very few games used every single book.
In my 1e experience, characters were straight out of the PHB . . .and maybe Unearthed Arcana. 1e lasted ~11 years from the release of the PHB to the release of 2e.
In my 2e experience, characters were made with the PHB and maybe a relevant campaign setting book or splatbook. 2e lasted around 11 years from the release of 2e to the release of 3e.
This is where I start to differ. While we avoided most of the splats, Tome of Magic, Complete Psionics, and the books about specialty priests quickly became quasi-core material.
In my 3.x experience, characters were made with the PHB, and maybe a couple of splatbooks or campaign books. I only saw talk of using "every" book in CharOp/MinMax contexts. 3.x lasted as a "current" edition from August 2000 until June 2008, that's a shade less than 8 years.,
The 3.0 splats didn't stand a chance at our tables, but the Book of Eldritch Might and Book of Song and Power (?) gained a prominent place. During the 3.5 era all payers were expecting the new splats like children Santa Claus.
I have no 4e experience, but I keep seeing talk about how characters are made with every book and how you need DDI to keep it all straight, and this isn't in a CharOp context, it's in regular gaming talk. 4e has been current from June 2008 and ~3.5 years later I'm seeing talk about waiting for 5e to reset everything again.
I think it's just the other way round. You don't need DDI to create and run a perfectly viable 4e character. But you'd have to develop an impressive level of system mastery to manually optimize him. DDI is an extremely powerful tool for CharOps and MinMaxers. Furthermore it makes maintaining a character and planning his career very comfortable. Small wonder that many (or most?) DDI subscribers don't want to throw away this level of comfort.
