It's possible, after all, the 3hr game jam exists. Though, I would question the level of polish on a game made in 4hrs compared to one made over the duration of a 15 day jam.
True, however I played one game a while back that was made in 5 hours, it wasn't super polished or anything but it was pretty good.
true, true, but I have seen some of those games pop up immediatly in other jams as well.
