Ones that are already ahead, and will stay ahead...

Nintendogs
Pokemon D/P
New Super Mario Bros.
Brain Age
Brain Age 2
Mario Kart DS
Animal Crossing DS
Wii Sports
Wii Play

Already 9 ahead of it, and 5 or 6 more either out recently or coming out next year which will have a chance to beat it... GTA4, SMG, MKWii, Wii Fit, SSBB, GT...

I'm going to go ahead and say this:

Halo 3 will not be one of the top 20 best-selling games of the generation.

The "generation" consists of all games ever released for DS, PSP, Wii, 360 and PS3. It does not include PC games from the same time period.

For reference, Halo 2 was the 8th best-seller last gen, and Halo the 13th.

Lets keep it on consoles.

Halo has to be some sort of freak of nature. The game got so much hype during the original XBOX launch. My friend got an XBOX for Christmas 2001. We both played it together that day, but in the end, I just didn't believe the hype. I never played it again until earlier this year.

Still, over the years, I watched in awe as the game kept selling month after month, year after year. Halo was jokingly refered to as the "only" game for the XBOX. In a way, it was. If you had an XBOX, you buy Halo. Halo 2 was a major step forward, but I never had any desire to play it. XBOX fans ate it up. The media presented it as the second coming, and to many, it was. I still don't think it deserved the hype it recieved, but it had strong multi-player. It satisfied it's fanbase.

Halo 3. I finally started drinking the Kool-Aid. The hype for this thing was like nothing I'd ever seen in my 25+ years of gaming. In preparation, I bought Halo and Halo 2. Halo 3, in my opinion, was a great game. I didn't dream about it when I wasn't playing it or anything, but it didn't dissapoint.

Long story, short. As the "only" game for Microsoft's hardware debut last generation, Halo recieved a lot of (in my opinion) undeserverd hype. So many games this generation are so much more deserving, but unless some new Pokémon type phenomenon is created, NO GAME (I can't count Wii Play or Wii Sports with a straight face) is going to beat it. *edit* In my rant, I completely forgot about the portable systems!

SMG : Little chance as it looks. SSBM : Maybe yes (SMG makes me doubt). GTA4 : Easily. GT5 : Probably. WiiFit : i'll go for a no. Wiisport/Wiiplay : Not relevant at all. It's pretty much a question of machine and wiimote sold. So "of course". FFXIII : Again, a matter of WHEN. IF it was release in Q1 2008, I would say no. In Q42008/Q1 2009, that's almost sure.

blah blah blah, I personally hated Grand Theft Auto 3. I hated Brainage and Nintendogs. Whats your point? Theres alot of people that have enjoyed 3 iterations now. Meaning repeat buyers, so its a popular no matter what you think.

GT5 and FFXIII no way I'd say, Wii Fit and SSB possible but not likely and the same goes for Mario Kart, the others I think will. GHIII could do it as well.

I'm sure there will also be some new ip popping up with incredible sales.

GT5

FFXIII

SSBB

WII FIT!

can't think of anything else

Carnival Games?

MY SENTIMENTS EXACTLY CAPS LOCK!!!!!1

Furrealz.

Hahaha... Don't count handhelds... Don't count Wii Sports/Wii Play...

Well, if you just don't count the most popular system of the generation, and ignore the two biggest system sellers for the most popular home system because they are "not relevant" (huh?), then Halo 3 is the most popular game of the generation so far! Wow!!! *rolls eyes*

When Wii Sports has sold 40+ million, no one will be able to pretend Halo 3 is more popular. And you can't disclude Wii Play simply for being inexpensive and well-marketed.

At the end of the generation, those who want an accurate look at the top 20 most popular games will not see Halo 3 on the list. Those who want to ignore Nintendo's repeated disruption of the market will no doubt find a way to put Halo 3 at #1.
