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.
Minecraft : 15€ spent, over 10K hours played and I only wish I had played even more !
Fallout 4 : 60€ spent, it’s boring.
FO4 is kind of bland by itself but it does have a lot of great mods. Horizon’s my favorite simply because it’s kind of designed to be a self-contained experience (even including texture and lighting mods by the same creator!) so it’s very much a quick and easy process.
