well buddy I am doing this for a long time and I usually try to avoid conversations like this but I have few hours free time so let's chat and have a friendly argue a bit shall we ?
it really does not matter how long you are working per day but what matters is that how much impact and progress you are making .
one day at work we were at lunch break time and we were chatting about stuff and I told my art artists that I really like someone draw a picture of me and one of my drawing artists drew my sketch in 3.5 min and colored it the entire process of making my ugly face and body for her was around 15 min
I am not really checking his stream or anything but when you see the outcome which is usually 1 hour play time and comparing to the time that he was making it you can estimated it
dc can make art in a day or an hour or in 10 min but at the end when I see the game and amount of content I can tell you how many hours he works (how do you say it English is not my main language sorry for miss spelling and grammars issues ) positively
right now it is around 2 hours for me per a day , I am surfing on this site for quite some time to see what people like and what they don't and see if I can bring some ideas to our games or even hire few good people to work with but as I said DC game is good but somehow in my mind and logic the amount of time that he puts on updates and contents are somehow not matching
