Warcraft III has aged like a fine wine.
It wasn’t just the progenitor of the MOBA genre (which still exists in a thriving state), it also rules as a standalone strategy game. Its marriage of RTS army macro-management and hero micro-management made it an instant hit from a purely mechanical standpoint.
That’s to say nothing of the aesthetic value of the fantasy setting itself, which has far evolved from the original “Orcs versus Humans” conceit. That test of time has only done Warcraft III: Reforged favors.
