Dang, Jones and Ben both put the most time into Octopath of the allies I believe. (maybe Brad)
It shows the UE4 logo every time you start it up lol
I have only put in 40 hours or so into Octopath (it's possible I will go back to it, but I got tired back then of grinding for 20 or 30 levels for the next party member to do his story part after doing that a couple of times already for other party members), but I do close my games each time and I didn't remember the UE4 logo either. They have played a lot of different games after they played Octopath, so I can totally see how they don't remember that logo.
I usually don't know on which engine a game is made. I like hearing about it, but I usually don't really care too much as long as it runs well. I usually turn my mind off when I see the same logo's pass by when I start a game and just ram on the X or A button until they are gone.
I usually also keep playing a game until it's done, although I do jump around a bit more the last couple of years. I usually only play one game at a time per system.
The exceptions are games like Forza which I do play once or a couple of times a week (usually for half an hour or so for the daily challenges) or games that I play while listening to podcasts (eg. at the moment, Trials Rising, SoulCalibur VI, Forza, ...).
