And that brings me to Tomb Raider. Popular series, but looking at NPD data going back to the PS1, the series doesn't appear to have any measurable impact on hardware sales. It probably does move some hardware given that it's a well-known and still reasonably popular IP, but the increases are small enough to where they're washed out in the monthly tracking. It's impossible to discern what's due to ordinary week-to-week random fluctations and what's due to a modest 25% increase in sales in a single week. Now that we're going into the holidays, the effects of software on sales will be even harder to determine, as we have to look at previous holidays to see if there's any appreciable YoY increases that cannot also be attributed at least in part to price cuts and big holiday sales. TR could theoretically move 20-30k units (just to throw out a plausible figure for a modest system-seller), which would have a barely measurable effect on a non-holiday month and would be totally lost in the massive sales figures that we see from major systems in November (the XBO will likely sell over 750k and the PS4 well over one million). And going back to Halo 5, if it does have a residual effect on XBO sales, that too will almost certainly be washed out due to holiday sales.
