688i was AWESOME ! I remember printing out the manual for it with my lazer printer and then having to have Staples mount it into two separate books because they didn't have binding combs wider than 1 1/2 inches !
I still play it sometimes. I have all the Sonalysts games installed on my PC's here.
To this day, I think the tutorial in the rulebook was WAY better than the tutorials in any of the sub games to come.
