You should charge hourly rate instead of by game. Some might clear all 5 acts and you sit there for 3 hours for 3fg bc you charge by game. Thats a big loss of time on your end. But thats your decision just trying to help out.
yeah, I thought about that but works better this way for me, because I'm charging only for the time to follow the game, once I'm in there, I lower the window and continue working

if it takes 3 hours, that's fine with me

Thanks for the heads up though !
