It's always hard being away from good friends for years and years. When you see them again a lot of times they have changed and aren't the people you used to know. The last time Ryu and the other World Warriors played a part in gamer's lives was 12 years ago in the various iterations of Street Fighter 3. When last you saw them they had changed quite a bit and brought lots of new people to the party. Lots of people didn't think it was the same as before, but those who stayed and got to know the new characters and moves were few and far between. Now over a decade later, Capcom wanted to bring people back to their childhood where things were much simpler and the faces were recognizable. Its safe to say, it is good to see old friends again.
