Tsunami was formed by former Sierra On-line people back in 1991 and was know for their adventures and interactive movies.
I played quite a bit of Blue Force which I really liked. It was designed by Jim Walls (designer on Police Quest) and the resemblance is pretty obvious.
I’m not really a FMV aficionado.. So I never played their FMV games like Man Enough, Silent Steel or Flash Traffic..but Man Enough does still look intriguing:)

Here’s the my almost complete sealed Tsunami collection (missing Return to Ringworld).
