Mean that just npc expense alone is 660k excluding a few here. Add on to that the cost of a full late game gear set being about 200k give or take then the cost of tf's to get a preferred look being anywhere from a few thousand to 100k depending. That means 1 mill is pretty solid and 2 is golden obviously though I need 50mil.Here's everything notable for gathering credits.
Included here is a list NPC expenses. Purchasable items, clothes and equipment would be WAY too much to list here.
Paige's eye replacement and surgery - FIVE HUNDRED THOUSAND!!1!! :O (still get sticker shock from that)
Ellie fertility treatment - 100000
Buying out Emmy's contract - Not currently available ingame, but she mentioned a penalty of 40000. Might be higher when/if she becomes recruitable.
Give credits to Saendra - Not currently available ingame, but that button is taunting me. Savin is master cock/cunt tease.
Impregnating Gastigoth prisoners - 15000 each for Tam-Tam, Khorgan and Sam. Once paid, it still costs 1000 to sex 'em. And another 15k if you want another baby with them.
Sera's merchant loan - 15000
Buying Sera's debt contract - 15000
Emmy's herm harness halfsies - 15000 (pricey toy, might have to force Emmy to go to business school. She can learn to budget more modestly >.>)
Embry's full transition in tips - 15000
Carrie's male milker repairs - 10000, you beast
Buying Yammi's freedom - 7000
New arm for Liliana - 6000 for regeneration, 2000 for cyber (heavily reduced in price by JoyCo, according to the Doctor Anilla)
Reaha's contract - 5000
Kase's Pryrite contract - 5000
Nipplelux for Jade - 4500
Erra's collar - 2000
Sera's shopping spree - 500 and that's after canceling most of the purchases (Sera, I'm going to tan your bottom! Couldn't you have just asked?!)
