Do you remember the year 1983, when Return of the Jedi was in theaters, The Police were still together, and Travis was still inside his parents' genitalia? Well Gearlog does, because they got their hands on an original 1983 Microsoft Mouse.
The green buttoned mouse was bundled with Microsoft Word, and came with the Life game, Notepad, and a musical tutorial teaching then-noobs how to use a mouse. Look how far they've come since then! Now Microsoft mice sport lasers, charging stations, multiple buttons, Bluetooth, and a scroll wheel, but are just as uncomfortable to use. Good thing their keyboards rock.
