Multipliers will just demonstrate how 'anticipated' a game was ...
Consider Brain Training in Japan, it's first week sales were 46,590 and has sold (after 113 weeks) 3,599,891 for a multiplier of 77.3; at the same time Dragon Quest VIII sold 2,267,827 the first week and 3,609,295 after 69 weeks for a multiplier of 1.6
Shooters probably have lower multipliers because they're tareting the 'Core' gamer who is probably aware of upcomming games (and will likely buy it early on) whereas a puzzle game targets more 'Casual' gamers who require something or someone to inform them that the game exists.
