You definitely have an issue, mostly because I wonder how on earth you have enough time to play that many games lol.
But your issue is also that you paid $60 for both GTA V and Assassin Creed Syndicate, no wonder you spend too much money on games, can buy those outside of Steam for cheaper, Assassins Creed for like half the price in fact. Use Kinguin, I have bought quite a few games on there no problems ever, they offer a protection for a very small fee so if you do encounter any issues with the key on Steam they will help you sort it out and get you a new key if need be.
I do spend a lot of time playing games, but it might be less than you think, I would say a rough average is 3 hours per day... Majority of my steam games I haven't played over a single hour, they are just there for collection purposes and a backup plan for that rainy day that never happens
I just like collecting them I guess... It's like a security net for if I lose my job or when I get old and my grandkids put me in an old folks home XD
I can always justify purchasing games in my internal dialogue by comparing it to other things I spend money on... It's kind of silly but I'm always thinking "Oh I spend $200 on groceries and thats all gone in like a few weeks... If I spend $200 on steam games I'm going to have these forever!"
Wish I would have known about AC:Syndicate for $30
GTA V was a stupid impulse buy... I was almost sure it was going to drop in price for black friday sale so instead of waiting 2 or 3 days and buying it on sale I just bought it full price... even dumber is I own GTA V on console sitting in living room
Kind of a disappointing purchase... Was expecting the multiplayer to be better, (hadn't played it since a few months after game released on consoles) but it's all hacks everywhere on PC
