Next, the title includes "STEx Collection Vol4 SimCity 4 Mods Disk 4 Download UPD". I need to define or invent what each part entails. STEx could stand for "SimTools Exchange" or "SimCity Texture Exchange", maybe a community project. Volume 4 suggests it's part of a series. Disk 4 implies it's the fourth installmentation in a series of mod disks. "Mod" would be modifications for SimCity 4, and "UPD" might refer to an update or patch.
