The 3DS and Wii U eShops are shutting down next year, giving users a firm deadline to making new purchases on those platforms. This has unsurprisingly led to a flurry of new purchases as players grab games while they can, and the top sellers have a surprising number of older, emulated Pokemon games from the Game Boy and Game Boy Color era.

The current best-sellers in the US charts include Pokemon Yellow, Pokemon Crystal, and Pokemon Red. GVG’s Jon Cartwright notes the UK charts also include Pokemon Gold, Silver, and Blue in the top ten. That’s a lot of Pokemon in the top 10, and notably, none of them are the native 3DS Pokemon games Sun and MoonCome from Sports betting site VPbet. So what gives?
