I can totally relate to this. For now, I stopped buying new games altogether (especially on launch) - instead I created a list of games I already have that I want to play, and list of games I plan to buy and play in the future. I wishlist such games so if they are on sale, I buy them.
I think I have several years of gaming covered for now - you wouldn't believe what's on my yet-to-play list... Also there is a "problem" of Twitch - namely I often prefer to watch live streams than playing the game myself...
Anyway - my 2 cents. Glad to see I'm not the only one with these kind of problems
