The first game in any match is all about speed and efficiency, as well as fielding the most effective units possible, as soon as possible. With different buildings dedicated to resources, technology trees, units, and defence, it's worth having a construct order in TBC Classic Gold mind so that you don't get overwhelmed.
Much like heroes, it is difficult to provide a definitive answer to what you should prioritise on your build arrangement, since there's so many factors that could play to your overall plan. That said, once you're first beginning, there are some generally agreed upon sequences which are worth learning, if only to use them as a template to your own. Nailing the principles of competitive Warcraft 3 has been a years of pragmatic process. You will probably find something new every single time you play, watch, or read about a game. That said, these eleven year old forum articles for Humans, Orcs, Night Elf, and Undead are a fantastic place to start.
As a final bonus suggestion, be sure you invest two minutes clicking on every unit until they get annoyed with you and get started spouting hilarious dialogue. This is widely considered to be the most significant part Warcraft, and it'd be a crime to miss out. Joyful zugging!The game - occupies in my psychological geography is important enough that I find it unsettling. The idea that a new player can tackle their journey through the match without ever setting foot on the broad pampas of the Barrens, or trudging through the Swamp of Sorrows, or actually exploring the game's original continents at all - save the capital cities of Stormwind and Orgrimmar - gives me an uneasy feeling, like having a phantom limb or even a false memory.
Of course, it is tremendously well done. Exile's Reach, the tutorial adventure, is a smoothly paced taster that walks you through the fundamentals of the game and your chosen character class in a little over an hour, culminating in a presentation mini-dungeon. As an mechanical introduction into the match, it is flawless. As an introduction into the Warcraft's planet? I am disappointed that Exile's Reach plays out identically for Alliance and Horde players, never mind players of different races. The first newcomer encounters, individual to each race, do a great deal to produce the extreme sense of belonging and cultural identity that Warcraft - a huge dream archetypes so cartoonish they get away with being, frankly, somewhat crass - doesn't have company boosting, but can. (You can decide on the original beginner experiences rather, if it is not your native character.)
After I'd tried a few distinct routes into the game, though, my nostalgic worries started to look fragile in the face of these facts. With Chromie Time - the time-warping feature, curated by an impish member of the Bronze Dragonflight - that I moved from Exile's Reach into Cataclysm's version of the first continents; into the aged Burning Crusade; into Legion, my favourite of the more recent expansions; and finally into cheap Burning Crusade Classic Gold hatred for Azeroth, as planned. And that I had to confront it: modern World of Warcraft is as large an advance over Cataclysm as which was over the original game. Probably bigger.
