If you both want, you can do the sharing program and let her play your games and her games will be available to you?

Just activate family sharing?

Refund Stardew Vally or FFIX if the playtime is less than 2 hrs.

Well, I think there's only one option - waiting for sale :/ I have similar situation 8$ on steam wallet and waiting for good price drop for game like Stardew Valley. Eventually exchange Frozen Synapse for game with valuable trading cards, collect more bundled games and keep collecting cards :) it's long boring work but after that you'll get game that you want :)

it's just $15 :|

if she's really that desperate to play, just pirate it, then buy if later when you can afford it.

Steam sale in 5 weeks supposedly.

Go on Tremor Games ( http://www.tremorgames.com/ ) and do enough surveys or other offers to get enough points for two - $5 Steam Gift cards. That plus your balance is enough to buy Stardew Valley. It should take you several hours, depending on the surveys you qualify for.

First world problems. Sorry I don't have anything useful to contribute to this thread.

as well as FFIX.)

There lies your problem you bought everything for yourself,you should have bought 2 copies of Stardew one for yourself and one as a gift for her,and if she did not want it you could have got a refund or traded for something.

All jokes aside there is no cheaper version i mean i suppose there are the grey market if you want to risk that but i would think the price would still be around 12 bucks as i think the sale price put it around 12 bucks when it was on sale.
Frozen Synapse is not worth much and if you got rid of pretty much everything else of value you might have to wait for summer sale and save a few coins in the mean time,this is why i only buy games really want to play,if i impulse buy then i would be short on funds all the time.

Also those multiplayer features i would not bank on them anytime soon giving one person is working on it i am sure that will take some time so if that is her main goal then she would be well ahead of the curve if she got it now.Also it is lacking in content and once you hit a certain point everything becomes really easy because of how easy money is and there not a lot of replay.That being said it still looks like a fun game and there seems to be some nice mods for it and even ones that add to the map and so on.
