The sales segment is pointless imo. Nintendo provides quarter by quarter sales info on all their software. MS has stopped giving numbers eversince XB1 massively declined. Sony only gives numbers whenever they feel like.
I think its best to look at ranges, bare in mind a fair amount of this is predicting LTD:
Nintendo
25-30M : Mario Kart, AC
20-25M: SSB, Zelda, MO, Pokemon
15-20M:
10-15M: Pokemon third entry, Splatoon, SMP
5-10M: LM3, SMM, 2D Zelda
<5M: FE, Kirby, Xenoblade, etc
Sony
25-30M : TLOU II (?)
20-25M: Spiderman
15-20M: GOW, UC4
10-15M: Horizon, GoT (?)
5-10M: GT, DG, Bloodborne, Ratchet, Death Stranding (?)
<5M: Gravity Rush, Team ICO, LBP, Infamous etc
MS
25-30M :
20-25M:
15-20M:
10-15M:
5-10M: Forza Horizon, Halo
<5M: Forza Motorsport, Gears, SoT, SoD, Crackdown etc
The metacritic score tracker is great. Really shows how Sony and Intendo have excelled in first party games while MS is virtually lost.
