Math

Sims 4 Base Game, Digital Deluxe = $70

EP01+EP02 = $40×2 = $80

GP01+GP02 = $20×2 = $40

SP01->SP04 = $10×4 = $40

Year One costs = $230/12 = $19.17 per month

Assuming we get the same number of packs in 2016 (but minus the BG price) 

Year Two will cost = $160/12 = $13.33 per month. 

– – – – –

That averages out to about $16 a month, very close to World of Warcraft’s $15 a month subscription. 

If you then divide up WoW’s previous biennial expansion price ($40/24mo) and spread it out, that adds $1.67 every month on top of the sub cost. 

(But if the new EP price of $50 is going to be the norm, that adds $2.08/mo.) 

There’s no heavy point to this post, I just didn’t realize that the (admittedly quick and dirty) breakdown of the two games would end up so similarly priced.
