For me it’s Team Fortress 2. $100 total spent on hats and the Orange Box back in the day, 4200 hours plus of fun, meaning 2.3¢ AUD per hour. Initially I thought DotA2 would be my best but it turns out I’ve spent a lot more money in that game than I thought…
My worst is God of War: Ragnarok. Bought it full price for $95 AUD, only played 2 hours and hated it, meaning $47.50 AUD per hour.
Gotta be BG3. Bought it full price the day I got my deck, about a year ago. There for a while I played every single day for hours. I still play a little most days, though it’s with my wife rather than solo. I can’t remember how many hours I have on the deck, and the ps5 version I eventually snagged so my wife could play has to have damn near half the time just from me.
