Definitely seems like Titanfall just wasn't the multi-million, system seller in the way that Gears and Halo were for Microsoft in the past. With the amount of marketing that game received, you'd think otherwise. I guess it doesn't help that the regions they are getting spanked in, just don't find that type of game all that compelling.
I've said it in other threads, but I can repeat it now:
In our stores, we've seen Titanfall sell well, the game definitely had some great sales the first couple weeks, but the bundles didn't really move very many at all until the 50 dollar price-match to WalMart kicked in. Then we started selling more of them, but still not at any kind of crazy velocity. They sold well. But the problem was that Sony started to stock our stores weekly too, and the PS4s still have the same kind of high end sales velocity they've had since launch.
And now, the 360 version is out, but every time I've asked other stores, and checked numbers... there's just not a lot of momentum about it. I had to inform several people I know that hadn't gone next-gen yet that there even WAS a 360 version. All the media has been about the X1. Informed gamers (enthusiasts), knew, but... That's not really the core metric for the CoD crowd TF is targeting.
Hell, I want TF to do well, new IP with promising talent behind it is great. But I feel like the way it was handled... is a disservice to the game, and to Bluepoint, at this level, cause they did a badass job with the port, and I've seen people actually mad that it exists, since they felt swindled. It's a stupid mentality to have, but, people feel that way.
