Brawl had a bigger opening than even Smash Bros. 3DS and Wii U combined, even with a smaller install base (8.8 million Wii vs 15 Million 3DS + Wii U) and during a non-holiday month. Now, let's look at 6 months into their lives, keep in mind, that both Smash Bros. 3DS and Wii U had the advantages of both a combined larger install base AND the holiday season.:
6 Months into lifetime:
Brawl: 3.3-3.5 Million
3DS: 2.4 Million
4.5 Months:
WIU: 1.6 Million
Though, I have to honestly ask, how many people actually think that a good portion of Smash Bros. 4 buyers weren't people who bought both of them? That's rather silly, i'd say that at least half a million of them have bought both.
(all numbers are based on available NPD data)
...and oh, Kirby is doing pretty well leg-wise, despite not having literal legs. Toad too! Codename BOMBA
