bazilisek: I don't know. I admittedly never played the MI remakes, but from what I've seen in various gameplay videos, it's pretty until it starts moving. Then it becomes just weird and floaty.
I'll probably pick up the remakes one of these days for the voice acting. But GK already has that, too.
It's funny you call them weird and floaty... imagine what someone younger would say of the originals. Blobby and jagged? I think your time period and nostalgia is coloring your opinion, which is pretty normal.
bazilisek: Aren't they already? $10 apiece on GOG, all dressed up and ready to go. In the era of faux-32 bit nostalgia, I honestly do not think the very solid pixel art of GK1 is dated; the dialogue portraits of the CD version still look pretty damn good. And gameplay-wise, GK does not really subscribe to the dreaded Sierra philosophy at all, so there are no major obstacles in this respect, either.
They all look ANCIENT compared to modern standards. Your nostalgia and the time period you have been playing games is coloring your outlook. If she wants those classics to be played by a modern audience and be preserved in better shape a remake totally makes sense.
Shit man even I have a hard time playing the two sequels, they've aged so badly. The original pixel art is kind of timeless I agree, but only if you grew up with it.
