Hahaha, that image perfectly describes what it's like to complete that game. I remember playing bioshock infinite the day it came out, and somehow managed to beat it in the same sitting (I had to skip a day of classes to do so). I finished that game incredibly sleep deprived, so I couldn't figure out if the ending was just that good or if I was just too tired to comprehend it. It was so good that the same week I slowly went and beat it again in 1999 mode. Such an incredible game. The DLC is also worth playing if you haven't already. Even the hoarde mode is fun.

I see that Pillar of Community badge, I know what's going on here
