did you make this thread to ask if they read the OP? haha :P

Yeah, I'll leave it at that.

Even there it was mostly due to bundles otherwise it would have been more of a gradual increase rather than quadrupling sales.

Anyways, how are we counting games that change significantly.  Fallout 3 for example.  Not sure what the first 2 sold, but I doubt it was 6 million.  Madden and Fifa/WE had a pretty big increase from the PS1 generation to PS2.  But there are so many of those games it wasn't an immediate jump.

Well Call of Duty wasn't an immediate jump, but it counts, so if Madden had a jump a few games in, it sill counts.

Fallout would be tentative, until we know the sales of the first two.

Maybe we don't know their sales but at least we know their reputation, and that reputation is (not 'was') great. Not that it matters here though...

Animal Crossing (N64/GC to DS) and Monster Hunter (PS2 to PSP) seem like good recent examples.  Handhelds ftw.

I did, and 2.83 million is a break-trough. It may not be blockbuster, but it was one of the best selling Metroid games.

Also Halo and Smash Bros are just less ectreme examples. Smash Bros wasn't that huge of a game on the N64, now it's the best selling fighting games. Same goes for Halo as well.

It doesn't matter if it wasn't a blockbuster. The first sentence made it clear this is about significfant sales increase over the previous games, which the game did not have.

Plus Smash Bros sold about 5 million on the 64, which was a breakthrough, and Halo 2 had in between sales of the first and third game, showing a progression, not a breakthrough (again, already achieved by the first game).

Try looking at sales of all the games in the series you want to list.

Well 2.8 million from 1.5 million is almost double. I think Metroid Prime made a significant sales boost over past titles.

I'll accept your logic about Halo and Smash Bros. I thought they would serve as less extreme examples, but I guess you want only the big cases. So I'll retrack Halo and Smash Bros.

However after FF, GTA, CoD, Forza, and Metroid, I really can't think of any franchises that had extreme sales breakthroughs.

I meant any game in the series before it. So since the first Metroid game sold about as much, the breakthrough wasn't there.

BTW, the Halo and Smash Bros thing was related to me mentioning Mario Kart as an odd case. It also broke through in the first game, but selling so many millions more this gen showed it broke through twice. If Halo Reach achived something like 15 million sales, compared to just the 8 million of 2, that would also be a double breakthrough.

As for other series, some have been brought up already, like Monster Hunter. Didn't break a million last gen, and now is a multi-million franchise.
