Topic (Sticky) Terran - Introduction
But there is currently an application on the apple store where there is actually a Starcraft II
Battle Simulator so say you are the Terran, and you will press on the units you want and it will calculate the vespene and mineral cost for those units and if you write in the enemies players, it will calculate who wins the match this is actually very useful
I'm trying to switch from zerg to terran just because of the diversity of this race and because I like many upgrades, but I'm having really hard time spending my resources. This "keep producing units at all time" is difficult. Many say that zerg is harder to play, but I can't seem to manage so many control groups that terran requires. And also you have to tell each scv what to do after he builds something (of course I use the shift commands multiple times), and I get supply blocked all the time. It's a horror...
I think you should emphasize the 2 most important parts of playing Terran more in this guide.
Part 1: Flawless Macro
Due to the less production ability Terran has to constantly produce units. This means supplyblocks, skipping production cycles and adding more production buildings to late have a huge impact on the game and can be game deciding. If you are supplyblocked as Protoss or Zerg, you can just build 3 Pylons/Overlords and build a !@#$ ton of units afterwards either with warpgates and chronoboost or with a lot of safed larva. Terran just doesn´t have this option, so any mistakes in macro hurt Terran really hard. I believe that´s the main reason why the orbital has the ability "supplycalldown".
Part 2: Strategy and Tactics
Like you already described Terrans have to constantly use his units once produced in a efficient way. The most important factor is to get a good position for engagements with your units to trade cost effeciently. That´s why good players in TvP wait at Protoss`3rd and 4th base to let the Protoss attack into your position, which automatically favor´s you. In TvZ you also just attack expandtions and fight on the edge of creep to get most efficient trades. Advanced players also use tactical elements, where they use medivac drops to distract the opponent´s army from your incomming push, so that you can get into a better position before your opponent is attacking your army. Denying scouting is also a important factor, because you want to hide your strategy and tactical moves as long as possible to give your opponent less time to react to it.
(Part 3: Micro)
This is less important than the other 2 things above but if you have mastered the 2 parts above Micro can improve your results by a lot. Splitting marines aggainst banelings/infestors, dodging storms, focusfire banelings/infestors with tanks, sniping/emping high templar, kiting with marrauder or banshees... The Terran units can imcrease the cost efficiently by a lot, when microed correctly. This can allow you to get on equal terms in macro with your opponent, but only if you don´t gather 2k ressources while doing this.
I play Terran since release and i never got borred of playing it. Doing the active part is a lot of fun and because Terran has a lot of options to go for and dictate the game how they like it you have the possibility to develop your personal style. Whether it´s focussing on early pressure using micro and a lot of tactical elements for action oriented games or if it´s expanding early and building up a huge army very fast for big attacks you have the freedom to do everything you want.
