Broodwar remaster was also good. If they faithfully uprez the graphics, fix severe bugs, and do nothing else then there’s hope. The 2D remasters have a good track record so far.
That said, had anyone played WC2 recently? It’s pretty rough. It’s fun for nostalgia sake and if you’re into the lore of Warcraft or the history of RTS, but it doesn’t hold up like Broodwar still does.
High res textures (especially normal maps) and higher quality/coverage audio really made game sizes take off. Unreal’s new “Nanite” tech, where models can have literally billions of polygons, actually reduces game size because no normal maps.
