There are several different intro videos for Wizardry 8 depending on whether you started with a new party or imported from W7 (and how you ended that game). I’ve created a playlist of them here: *** Sorry, I don’t have enough rep to post links but if you search for ‘ @trachten59’ in Youtube you can find the playlist ***

most people just start a new game without installing / playing the trilogy

still here is the link to your youtube account https://www.youtube.com/@trachten59
