Well I hv played Fifa series for quite a long time now rite from FIFA-99,FIFA-2000,FIFA-2003,FIFA-2004 and the latest in its categories of Improvements FIFA-2005.
Well the EA wallas r doin a good job interms of tuning up the GRAPHICS and the GAME DIFFICULTY.
The earlier versions only concentrated on scoring GOALS (like the FIFA-99) series but from 2000 onwards(i mean FIFA-2000) they hv included graphics as an integral part of game development.
FIFA-2004 concentrated on OFF-THE -BALL-CONTROL while FIFA-2005 has laid emphasis on ON-THE-BALL and FIRST TOUCH CONTROL properties.And tell u wat both of them hv sum really gr8 graphics.But a lot of SIMILARITIES between the 2004 and the 2005 versions.
But nevertheless FIFA-2005 ROCKS !!!!!
