Captivating from start to finish - I went into this expecting cinematic and graphical reworks, what I found was so much more.
In mission one, the rework of the opening cinematic was as good as I expected, but I was pleasantly surprised when I could opt out of the narrated tutorial that the prologue offers - as an RTS veteran, this narration and guidance takes away from the immersion so that was an excellent quality of life improvement. Through the mission you are presented with three brand new cinematics that are reworks of what were originally just dialogue sequences. Another great addition are the codex entries scattered across the map, as a lore fiend myself I enjoyed taking in additional background and world building elements.
In my first playthrough, I accidentally had the campaign set to "Story" difficulty, which seems to be what Warcraft 3 defaults custom campaigns to. Upon switching to hard, you encounter additional creep spawns which helps to render what was once a skippable mission into something much more.
Mission two thankfully allows you to skip the base building tutorial as well, major win for veteran Warcraft 3 players! Another changeup that I was surprised by was the map was largely reworked from the original. The new layout felt more believable and Southshore was made to feel like a truly lived in town. There was also a nod to Jesse Morales in the graveyard, who was a Blizzard employee that is also honored in WoW in Southshore.
The cinematics are all reworked quite well, and the arrival of the Horde feels more believable and is presented as if some time has elapsed.
These missions of the prologue have always had a special place in my heart because two decades ago it felt like not many people even knew about their existence as they had originally only been available in the Warcraft 3 demo.
This was the first mission where the map was completely reworked and no longer bore any resemblance (terrain layout wise) to the original mission. The combat with the Humans is much more in depth and you have an added goal of saving troll villages along the way.
The Human Kul Tirans have custom unit models and their replacement for the priest, the Hydromancer, is a force to be reckoned with.
The more troll villages you save here, the more you'll have access to in mission five.
This mission opens up with something of a mini-game akin to the old StarCraft map "run zergling run" - although a bit more forgiving. This was an excellent break in the pacing and a fun start to the mission.
The map has a completely new layout from the original and is substantially more difficult. The mission ends in a boss battle that in some ways reminded me of a WoW raid. This was lots of fun and a great addition - although, Warcraft 3's pathing feels a bit clunky for the task at times (admittedly, I may have been spoiled on StarCraft 2's pathing over the years).
Mission five is the most intense "survive for X time" RTS mission I have ever played - which is a good thing! In the original game I went for a total annihilation of the enemy. As far as I can tell in Re-Reforged, completely destroying the enemy would not be in the cards.
The opening onslaught alone has to be carefully executed and each gold and wood is important. The fight to the end will keep you on your toes and optimizing each grunt, spearman, and even peon to achieve victory.
I would argue that Warcraft 3: Re-Reforged is the definitive way to play through the Warcraft 3 campaign in the modern age. I still appreciate, and at times prefer, the original graphics of the game - but there is no doubt that this modern cinematic rendering feels like Warcraft 3 has truly been reforged.
