Agree with you for the VGA, I've a real PC-XT with a VGA card but only to connect it on a "recent" monitor, not really to use the VGA resolutions / nbrs of colors.
You should test some EGA games, you'll be surprised the things an XT can do, many EGA programs and games up to 1992 will work very well, even VGA ones.
Also I'm not saying this core should have a VGA, (I'd do it, if I knew how to
). And it does not matter the VGA being a 16 bit card, they work ok on 8 bit ISA. just check a computer called PC98 from Japan (8086 8Mhz + VGA)
(EDIT: that pc98 was updated many times, some models have much more powerful graphics, so some games look too complex and can't be compared with an 8086 + VGA).
After 1992, games and programs start to not-use hardware functions of VGA, and just redraw the whole screen. It can be done in CGA, but a VGA screen is 64k... so XT's can't handle that.
About EGA.. just forget EGA, that card was available for a very short time before being replaced by VGA, which is an EGA card with bug fixes and the 256 color mode.
