Okay, MGS2 on PS2. That definitely sold systems as did MGS4 on PS3. Gta 4, I remember a lotta people rushing to get one for that. Bloodborne, The Witcher 3 and MGS5 in 2015 around that period for the ps4 it started to become nessesary for people to upgrade, can't really tell if it sold system though but Uncharted 4 the following year definitely did.
Breath of the Wild for switch. Twilight Princess and Wii sports or wii.
Halo CE for Xbox plus every Halo in the future up until like ODST. FORZA games too.
The 4x genre for PC or games like Civ and the like.
