Oh.  Well, that significantly drops the number of answers.

Frankwho

Right. Although I'm still interested in Remellion's solutions.

I see the intended solution but I too am wondering if there are others:

1.e3 d6 2.Qh5 Nd7 3.Qxh7 Ndf6 4.Qxg8 Nxg8

Frankwho

Yep, that's the intended solution. I don't think there's another solution, but I can't be sure...

Okay, I found his idea:

1.e3 h5 2.Qxh5 Na6 3.Bxa6 Rxh5 4.Bf1 Rh8

1.e3 Na6 2.Bxa6 h5 3.Qxh5 Rxh5 4.Bf1 Rh8

Nice job! I guess the composer didn't see that.

One of my favorite PG's ever is a 4.0'er:

P. Hoffmann

PG in 4.0  b) -Qd8

Frankwho

Answer in white:

1. d3 e6 2. Qd2 Ba3 3. Qb4 f6 4. Qf8+ Bxf8

I'm not sure about b.

These were a bit hard to find. 

I do like that study, BigDoggP.  You remove just one piece and the action flips horizontally but uses the same motif.

Yep - the twinning is ingenious.

I like that pattern.

Remellion

Another classic 4.0 theme.

Geza Schweig

And for those who missed the chance to solve what GreenCastleBlock posted, here's another 4.0. As an aesthetic bonus, it's an SPG - no 3.0 solutions for you here.

Is anyone going to solve these?

Good job! Here's another one (it has a cook though):

bangalore2

d3 d5

Qd3 Qd7

Qxd7 Kxd7

d4 Ke8

EDIT:  I don't know what I was thinking....

Frankwho

Please make your notation clearer. 2. Qd3 is illegal, and 3. Qxd7 is illegal.

caveatcanis

1. d4 d5 2. Qd3 Bh3 (or 2...Bg4) 3. Qf5 Qc8 4. Qxc8+ Bxc8
