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.


Most value is probably Awesomenauts at around €50 spent and 1950 hours coming to 2.5c/h
Team Fortress 2 is there for me too, about €100 spent and 2200 hours for a shocking 4.5c/h. Still play it to this day.
Minecraft is also around the somewhere but like everyone else I have no clue about hours played. Might be anything from 500 to 2000 hours, impossible to estimate. Since I got the beta or alpha for cheap, I think €10, it might top the other two.
My worst value game is definitely GTA 5. I think I got that at €50 or so directly from Rockstar and only played it for an hour online and like an hour singleplayer. I enjoyed gta in the past but just don’t care for it anymore, got bored out of my mind. Least time I ever spent on a game that expensive without being able to refund.
