LMA is released in the UK on 12 March - a week on Friday. It's then released Australia/NZ a week or two afterwards. European versions (Football Manager Campionato 2004, Roger Lemerre: La Sélection des Champions 2004 and BDFL Manager 2004) will also be released on 12th March as usual. Manager Da Liga 2004, the very successful Spanish version, will be released on the 15th.
Anyway, back to the topic...
You can import it to the US via Amazon I'm sure - just remember that it's a PAL system PS2/Xbox game so I guess you'll have to have a chipped console to play it.
