ALL DND games had Party of 8 possible slots long ago. You just created 6 of them and tehre were 2 free spots for NPC to join your party. Basically all of the TSR DnD titles.
Those were the days, were they not? Great stories, great design... crap graphics, admittedly... but those games endure in the hearts and minds of those who were lucky enough to play them when they were new for a very good reason. You could create and control a full sized party of 8 with versatility and utility (which you typically needed to do in order to survive) ...and you didn't start off with a 1st level companion character that had a 20th level background origin story.
