Tomb Raider was a failure when it came out technically, despite the fact it made over 3.4 million in a month, Square Enix didn't make their money back.
They are making a new Tomb Raider still though.
Sales and sale figures, if companies like EA are smart, will never hit the 1 billion mark like Call of Duty or GTA, which are anomalies in the gaming market. RPG's especially won't likely hit it.
Hell, the best selling RPG of all time is still Pokemon as a Franchise, roughly 30 million for the first generation, and still pulling in over 15 million in sales with each generation. As much as I love Dragon Age, no BioWare game is ever going to hit those numbers realistically. Even Elder Scrolls has only recently cracked 30 million sales as a franchise.
I think EA and BioWare realize that too. Check out how low key the marketing campaign was this time, which eats up a lot of the budget for most games.
My guess, Dragon Age is going to recoup sales and losses through multiplayer purchases over time, and it will lead to the series continuing because it is a successful franchise with more than just games out there. That is why the sales don't matter.
Well. If you look at successful franchises like CoD, GTA, TES, Pokemon, etc, they actually have some common properties.
...Which EA have never respected.
The first is that their sales volumes follow a stepped ladder through the sequels. The best and most celebrated installments are not those that sold best. Look at the contrast with EA's games, where the best game (usually the one mainly developed before EA purchased the studio) tends to also be prominent in the sales. Quality of the single game is not what drives the sales of the successful franchises though.
Mindshare does.
The first game sells like 1.5 - 3 million. But it gets a solid reputation. The word goes around. When the sequel comes, all the original customers buy the game. But there are now also many others who recognize the title and decide to bite this time. When that game also delivers, the reputation grows even more. The next installment sells even more. And so on, as long as the sequels respect the franchise and remain true enough to it, to sustain the reputation.
Which brings us to the second property of successful franchises: They are true sequels. They offer very similar gameplay ideas and gameplay mechanics. They are evolved, of course, changed. But they do not tamper with the central ideas of the game, the mood or the details and mindset which are central to playing and enjoying the game.
This is the opposite of what EA typically does. EA tend to treat a sequel as just the title. They always figure they will be more successful with a completely different game for different gamers, because they somehow figure the first game excluded all those who didn't buy it.
