Mediocre to bad series that became good to great in following console generations?

Street Fighter. The first game came out in 1987. Ported to the PC Engine in 1988. This game is terrible. Awful. Capcom knew it. 1991 Street Fighter II. Genesis and SNES were out. What else is there to say? Well maybe this. Both supported online play with X-Band on SNES and Genesis.
