@Final_Fan.
I agree. Just look at Halo 2 attach rate, it's 35 %. The best selling FF is FFVII and that has LESS than 10 %. Even in Japan, its strongest market, it has less then 20%.
Halo was actually more important to XB than Mario Platformer was to GC!
I mean, come on! 22% of XB's software sales were from Halo 1 and 2!
FF was on Ps, over 4 games, still only 7 %.
