On the topic of the top-selling game in 2008 ...
Over the past 12 years, the top-selling game each year has either been Pokemon (6, no third games), Dragon Quest (2, possibly another with DQVI in 1995), Final Fantasy (2), Wii Sports (1), or Animal Crossing (1). For this year, Monster Hunter Portable 2 G is currently #1 (2.44 million), and it's pretty much through for the year with its BEST re-release having been released this week.
Can anything catch it?
#2 in a few weeks will be Pokemon Platinum, but it'll be almost 600K behind. Does Platinum have 600K in it for the rest of the year? I don't think so. Animal Crossing Wii? Nah. Anything else likely this year? Nope.
That means that Monster Hunter Portable 2 G should be the top-selling game in 2008.
* First PSP #1
* First Capcom #1
* Fourth Sony system #1
* Eighth portable #1
Yes, that's because some game with a IX in its name got delayed
