I've got to say that I am disappointed that anyone would give this game 5 stars.
Apart from the well publicised stripping down that EA seems to have done for all of their 360 release day titles, I thought Tiger 06 on 360 is decidedly average. No new break throughs in game play and while the look of the game is better that ever before, it still doesn't conjure up the kind of Next Gen feeling that CoD2 or Perfect Dark do.
Oversights like the power boost button being placed on the left Bumper and the tiny in game text, which is illegible on my 28" Sony TV meant that I found it very hard to enjoy this game and took it back without delay and swapped it for Fifa RTFWC06, which is also stripped down, but in my opinion is infinitely more enjoyable from the moment you take control.
Don't get me wrong, Fifa isn't going to redefine the path of gaming, it too is pretty average, but it's just more fun to play.
Avoid Tiger 06 if you are used to the previous versions, if you aren't and you like golf then give it a go, if you have a spare £50 knocking about. Otherwise my advice is to wait for the 07 versions of ALL EA games on the 360, when I confidently predict they will be back with a vengeance.
