I'm not really a fan of this type of RTS, but the story and world was interesting enough to keep me invested. One issue I had was Arthas' corruption being far too abrupt. It seemed like he went from being a goody two-shoes paladin whom could do no wrong to purging an entire town all too quickly. And it did. He was purely a hero for 5 short, introductory missions and suddenly became such an extremist out of nowhere. Maybe he was always this extreme, but even still, proper motivation like a supporting character being killed, or something else personal, as a catalyst for his entire personality seemingly 180ing would have been nice. Hell, it would have been nice to just play as him as a pure hero for a bit longer, so the change and his actions were more impactful.
I just wanted to get that out there. I love heroes falling to villianly stories but this one seemed a bit forced. Still liked it though. I just wish it was better.
Has an absolutely superb soundtrack and possibly the greatest cinematics ever in game.
