Here's a little exercise I've been playing with for fun. While I need to hunt for bugs, I figured that I might as well pass it by here as an interesting (if ultimately useless for serious purposes) visualizaton to show one aspect of how a selection of consoles are doing. I originally tried to guess week-placement of titles that were listed as >1M in a year but lacked a specific known weekly date, but on reflection that felt like cheating. I'm now only incrementing those at the end of the period (year/half-year) they're reported for. One rare exception is FFXV, as it's recent, and a dirty guesstimate seemed more interesting for the moment (and it was just 5k away with 1.5k-2k sales per week in the last weeks it charted).
Among the things I've so far been unable to peg down: Did NSMBU cross a million at retail in Media Create? It's listed as so (per Famitsu) in the Games Data Library, but for the life of me I couldn't find it in any of the Top 500s in GAF.xlsx or the 2017H1 that GDL posted. [WIU] Super Mario Maker is also something I was wondering about but couldn't quite peg down for sure in MC.
NB: It's currently counting two separate Wii Sports Resort skus, and there may be a small number of similar issues that may account for some seeming inconsistencies. Anyway, I enjoyed digging around and throwing this together and am definitely interested in constructive suggestions for improvement if anybody else out there finds this sort of hunt as fun as I do.
