Starcraft – the type of Starcraft 2 games where you have a fixed amount of resources

I am not able to test it right now, but shouldn't double-clicking on the building select all similar buildings, and then right clicking on the location you want to rally do exactly what you want?

Alternatively selecting each building you want to set the same rally point holding shift should, afterwards again right klicking to the location.

Alternatively, you could add additional buildings to a control group later. Select the first building, then ctrl+#. Then select the next building, and shift+#. You can use shift+# to add additional items to any control group.

Using the numbers tzenes gave:

• Start out with 8 mineral patches, each with 1500 minerals
• Start with 6 SCVs (right?)
• An SCV takes 22 seconds to build
• The first 2 SCVs on a mineral patch will gather 45 minerals a minute each, while the last one can be considered to gather about 12

In other words, there are 12,000 total minerals to gather; the first 16 SCVs will gather 45/min, the last 8 will gather 12/min. Using this knowledge (and not taking MULEs into consideration!), we can construct a table:

 Seconds  | Number   |  Resource gather rate  |   Total minerals
 elapsed  | of SCVS  |  (minerals / minute)   |  gathered (approx)
------------------------------------------------------------------
        0 |     6    |          270           |        0
       22 |     7    |          315           |       99
       44 |     8    |          360           |      214.5
       66 |     9    |          405           |      346.5
      ... |   ...    |          ...           |      ...
      198 |    15    |          675           |     1485
      220 |    16    |          720           |     1732.5
      242 |    17    |          732           |     1996.5
      ... |   ...    |          ...           |      ...
      374 |    23    |          804           |     3672.9
      396 |    24    |          816           |     3967.7

So at the time your 24th SCV is built and you become fully saturated, you could have mined about 3968 minerals. The remaining 8032 will then be mined in about 590 seconds, giving an overall time of 986 seconds, or about 16 and a half minutes.

Of course, this is a lower bound. In a real game, the actual time will be slightly longer because:

• Some SCVs will be building/scouting
• Some SCVs will be mining gas instead
• Not all mineral patches will deplete at the same time, so your resource gather rate will actually go down near the end. Hopefully by this point, you have several other expansions :)
