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: Terraria on PC. I paid $5 during their first big sale on Steam and have like 500 hours in it so $0.01/hr (1¢/hr )
Least: Spawn for the PS1. I got a special launch version that was $60. I hated it after 20 minutes and was full of regret. That’s $180/hr
