Let's keep traveling back in time until we've covered every last great anime ever made, shall we? 1994 didn't have such a bad showing itself, with 4 shows still alive at the time.
1. Ranma 1/2 ova's
2. Fatal Fury the Motion Picture
3. Macross Plus ovas (start) + Macross 7 tv (start)
4. Yu Yu Hakusho (end)
Ranma 1/2 is the best series that was made in the past and hasn't received a remake in the future. As a result, it's probably going to be in the top spot regularly moving backwards. There really isn't much more to talk about beyond Ranma 1/2 once you get this far back in time.
