Warcraft III Reforged is doing a bit more than adding textures and changing character models. There are also going to be references to World of Warcraft, with a few things getting reworked to fit in with what happened next.
In an interview with Kotaku, executive producer Chris Sigaty and QA lead Nicholas Louie showed the map of the level “The Culling” which is a pretty important moment in not just Warcraft III, but in the lore that is built from there on. This pivotal moment has been rebuilt in World of Warcraft with two dungeons, and the design team wants it to reflect closely to those WoW versions. Like the Culling of Stratholme dungeon in the Caverns of Time, where you join Arthas, you will visit Crusaders’ Square and other locations where there were boss fights.
Besides map reworks, the team also wants to flesh out characters who became much more important later on, like Sylvanas Windrunner and Jaina Proudmoore. “We’re also looking to flesh out characters that… we were unaware they were gonna blow up. Characters like Sylvanas [Windrunner] and Jaina [Proudmoore]. In the events of Warcraft III, they’re not these huge, pivotal characters. It’s important to us that we bring them into parity with their presence in WoW in terms of importance. Their characterization time, their big character moments.”
At the same time, the team is aware of the dangers of changing too much, and the team includes several members of the original Warcraft III development team. The team also has access to the original code and assets. This means they can work with original files and systems, instead of observing them and trying to recreate and replicate them.
