I don't see it anywhere but it seems like it should be included according to the collection description.

Thanks,

Yes, the collection comes with the original EGA LSL1 in addition to the VGA remake. (Or, to be more accurate, I know for a fact it used to come with the EGA version when I got it and I don't think they would have stopped offering it).

Yes it does include both. If you use Galaxy, when you go to LSL1, there will be two white diamonds and the number two to the left of "Overview" at the top. Clicking on that gives option to select either one. One is the EGA (still uses scummvm and not DOSBox), the other has VGA in its title and is, indeed, the VGA version (and uses scummvm as well).
It has been a while since I used the manual downloads, but I assume it is included in the manual install together with VGA since there is not a separate installer for each. Maybe someone else can test that on a desktop without Galaxy?

They are two separate games in the manual desktop downloads, "Leisure Suit Larry 1" is the EGA version, and "Leisure Suit Larry 1 (VGA)" is the VGA version.
