gud news its one ov my favrite, bt where is ff8 th best one?

Lol, what's Resident Evil 5 doing in that list? :P Now they'll never go back to their roots :( (My favourite RE games are RE1, 2 and 3 :P)

And no MGS1-3, FFVIII and FFVI? :(

Well, at least the list isn't so bad in my opinion... compared to other lists I've seen... this one could be one of the best :P

Not much love for older games.  

Monster Hunter No.1 and Dragon Quest IX No.2?!! Should I be suprised or was this an obvious thing?

Good to see MGS4 in top 10

*Sees FF13 above all other FFs*

*Sees Resident Evil 5 made the list at all*

*vomits*

 I think it’s nice that Japanese gamers are open minded to new games but older ones are still popular enough to make in that list, like Xenogears.

  I personally like that FFXIII made to that list, since I pretty much enjoyed the game from the beginning to the end (aside from all the negative reviews from western reviewers and gamers). From all of the three final fantasies that I finished (FFX, FFXII, and FFXIII) it was the most enjoyable one just a tip ahead of FFX (I personally dislike FFXII).

  It’s also nice to see Okami, three "Tales of" games and the first Kingdom Hearts instead of the second (At least in my opinion the first was way better). I only wish that Shadow of the Colossus made to the top 20...

ff13 is a good ff, but its not nearly the best ff-

I won't say it the best overall FF games(tie between 7&10 for me)

I'll say it has the best battle system of all the final fantasy games (IMO)

Pretty interesting list; it's pretty much what I'd expect from Japanese gamers.

It's surely because it just came out. Same thing for DQIX.

But at least FFX is #4 :)
