I honestly don't know why I continually purchase games when I have so many others to play through. Maybe I have a problem, I just like to buy games, it makes me feel "good" especially when on sale. I even buy last gen games when on sale .
I'll say this, going into this year I promised myself I would take a Sandy Alderson-esque approach to buying games and buy and large I've stuck to that. Didn't get Monster Hunter World or Bayonetta 2 for Switch. So far the only games I've pre-ordered have been MLB The Show 2017, God of War, Sea of Thieves and Burnout Paradise Remastered.
I've picked up Hellblade Senua's Sacrifice, Observer and Sundered on the cheap. Bought Mass Effect 2/3 and Dead Space 2/3 on the cheap as well. I've been strategic on what to buy and play this year early on, playing through some of my backlog and waiting for sales on games.
Usually I would pre-order and get stuff day one, only to see the prices drop a couple months later. Now I'm just waiting to see what I can nab on the cheap or on sale, waiting for the market to come to me. Like I said, Sandy Alderson-esque.
