Nothing. Consider ITNOTE as the byproduct of the development of some EACW missions.
ITNOTE is outlined, and meant as an EACW crossover campaign. I will do ITNOTE eventually, AFTER EACW is finished.
I didn't desert EACW, just made ITNOTE in a few days ( within a week I think ) so I can release SOMETHING. Its an introduction to the centauri, and a test, since you get to fly a SENTRI in EACW as well, and the player's ship in ITNOTE, the CENTAURUS, is also featured in part IV of the civil war campaign.
You meet your alter ego.
