A disgusting amount. My 10 year old Steam account reports €1940 - €6024 (lowest known prices vs. todays price) on the Steam Calculator. My Megami Tensei collection I've spent well over €1000 on, though the price of most of the items I own have doubled since purchasing them
Hmm somewhere around $45USD. Spent $35 on Apex Coins and $10 on EA Origins Access so I could get the Apex Legends Battle Pass. I got so much games in my backlog, I’ve made a commitment to clear it before buying any more games.
