Unfortunately with AAA games there are different expectations these days internally what is a flop and what is not.

From a gamers point of view, Using old standard thinking that we've used for quite a while, 1 million in 1 month would be considered very good. But as we know from the sales of Tomb Raider, where they had sold 3 million in a month, they considered that *bad* that it hadn't sold 4 million. 

So first thing is that the numbers we think are good are not necessarily good in terms of the sales the companies expect.

As far as we know the team working on TF was pretty small, MS paid for exclusivity and by the looks of things paid a lot of marketing (which is extremely expensive), so it may well be that even though EA/RS will be disappointed with the sales (especially 360), they may be happy with it, because many of the associated costs of releasing a game have been paid for by MS.

As far as MS is concerned, then its not been great at all, to bundle the game for free (for what was considered best game ever by the gaming press), and for it to bot push massive amounts of hardware, seems bad. For them to bundle it for free and for price drops to happen in UK/USA - very very bad.

So overall I think it will be like this:

EA: Generally happy, but will not do exclusivity again.
RS: Not happy with EA due to exclusivity, but happy with the sales.
MS: Not happy at all.

PS- as for the press they should have been ashamed of themselves how they handled the whole Titanfall review stuff.

Why would the press be ashamed of themselves?  By the overwhelming majority of the feedback from those that actually own the game, it delivered what almost all critics proclaimed.  How can the critics be held accountable if the game hasn't met the hype (mostly by internet fanboys) that it would sell 2-3X what it has.  Most people can clearly see that you are right on the Bolded, but claiming that your opinion that the game is not good doesn't make the reviews invalid.

Uhmm..yeah....its an ok game to me...but i think the expectations were too high to begin with...

I've also noticed at many resale shops that titanfall is starting to show up almost as much as knack...

Probably a flop to Microsoft at least in the UK going by how much titanfall bundle stock there is in the UK.

Also a strange title to promote on xbox one when its technically one of the xbox one's weakest games and MIcrosoft are trying to fight the accurate perception that the ps4 is more powerful.

I think there is geniune desire to see a proper full Titanfall game with both online and offline gameplay. I think Titanfall 2 could be huge.

I'm not planning to buy xbone yet but even if I did I would avoid this bundle. I never subscribe to xbox live and never have. So personally I think its done very well considering many will not be able to actually play this game.

I think in the next few months we will see huge drops in the price of Titanfall in the UK for retail copies. If Microsoft have over-estimated the impact of the game for its bundle so have manufactured too many bundles they may have done the same with the game itself with EA making too many retail copies.

I think you nailed it....I´d just change the Disappointing to a YES .

The technical state it released in and the effect it had on XBone sales were just disappointing.

There is only one King of Kings

It's a bad game
Sales or no sales..it's a flop in my personal gaming world.

Not a flop at all. It was just expected to do way too much.

I learned  from sales2099 that a game can still be a flop, despite good sales. For example, he's said that GT6 was a flop, despite selling a few million copies. That was because it "performed below expectations". Since it didn't meet those expectations, it's a flop.

By that same token, Tomb Raider sold what, 4 or 5 million, and SE/Crystal Dynamics were still disappointed with its sales (did it fail to make a profit? I don't remember)

So, here we have Titanfall at a cool 1.55M across all platforms (until 360 numbers come in). What were the expectations? 6 million shipped by years end (by the way, those are EAs expectations, not PS4 owners)? By the way things are looking, unless the 360 version performs similarly to the XBone version, then TF will be a flop by that "definition".

I personally don't think it is one. 1.35M is great, especially on an install base of 4.2M (32% attach ratio!). But apparently those kinds of sales don't necessarily equal profit (looking at Tomb Raider) and it's far below sales expectations right now (2.4M shipped by the end of the fiscal quarter. 1.55M total sold. 0.85M sitting on shelves?) so if someone wanted to call it a flop, I wouldn't argue.
