Probably not as I didn't buy it with DM content either. 3.5E is enough to fill my D20 needs.
I did buy Shadowrun though. A complete game for $60.
First, Shadowrun does not have the same challenges D&D 5E has.
D&D has a large fanbase that loves a huge number of aspects from separate (and often disparate) versions of the game. It just plain has more stuff that players over 40 years consider deserving to be in a PHB1. Shadowrun was never that big in its core. It had one lore, and the same core concepts that it would fiddle with from edition to edition.
In order to give D&D players the lion's share of that player-desired content at the start of the game, they have to fill up the PHB. That's how I see it.
I *want* a book filled with content for Players. I *like* the demarcation of content. If you are a player of a game, don't you want more player material in your Player Book? You don't need DMG material. To many players it is a waste. If I am a DM, I want lots of quality DM materials. A full book's worth, please.
The first 4E PHB didn't have Bards and Druids and Gnomes and other stuff. There was an uproar. So with 5E, they are attempting to put that all into one book. That's going to take space.
So, would you rather that the 5E PHB cut some player content in order to put in DM advice?
I will repeat a question to you that you ignored previously.
What would you remove from the PHB to fit DMG materials in the book?
