I think if pokemon were real it wouldn't be any fun because some corporation or legal group would try to control them and they would probably be successful at it. They'd be used for war purposes and every attempt would be made to keep them away from the general public.
Pokemon fighting would be made illegal and it would have the same reputation as real life dog fights. It would be frowned upon.
Having a pokemon would be like having drugs and it would probably be seen as something "bad people" partake in.
In other words it would be boring and downright painful for a pokemon fan if they suddenly became real. Too many peoples morals and greed getting in the way.
