Some of you may know that for the past sixteen months I've been running my own statistical sampling of Steam data, in the manner of Ars Technica and SteamSpy. Last week Valve made some minor changes to one of their error pages which necessitated a change to my sampling code. Whilst investigating what had changed I noticed that I can see Steam wishlists and lists of followed games on public profiles, so here's a graph of the number of people who have wishlisted or are following (or both) a selection of upcoming games including Total War: Warhammer, with Total War: Attila and Total War: Rome II thrown in as well for comparisons sake. I'd caution about reading too much into these figures at this stage, but I plan to keep updating them and hopefully they'll reveal something of how well (or badly) Total War: Warhammer is being received prior to release.
Important note: I introduced a small bug into my analysis code when I updated it, whereby the new error pages were not included in the count of sampled pages. This resulted in the previous graph I posted showing figures approximately 25% higher than they should have been. The new graph contains corrected figures.
