I was curious as to how the selection box was going to work in the finished product. Personally I prefer TA's how you could start somewhere and move the screen while the box would expand with it. It is quite inconvenient trying to select a large group of units (not a problem yet but in a large game it could be) and the selection box stays the same size while moving with the screen (possibly) rendering you unable to select all of the units aforementioned,which could especially be a problem if someone were playing on a lower resolution.
