Pro Evo 2009 was given 3 stars by the press, and it said that it wasn't improved much and it isn't very good

that feature was only in fifa 2004 where if you owned both games you could 'fuse' them.

for whatever reason they got rid of it

There is such a thing max. It is with the manager game that i used to use, and you got in Malta. It is called FIFA football fusion and you manage using the manager screen and play the games using fifa. I never used it because i never had corresponding games, FIFA 2005 and the managing equivalent, i have duely forgotten the name by the way.

FIFA is quite awesome, but I would like to see a combination of FIFA and a manager game, so you had the choice of both or one or the other. That would be awesome

neither can be claimed as better than the other.

pro evo is superior gameplay
fifa has better everything else

so its a personal preference type of thing
