LEEEEEEROOOOOY JEEEENKINS!

...but yeah, personally. In my teens I used to play World of Warcraft (TBC era) like a maniac. I remember playing Arena PvP in 3v3 and 5v5 with a complete misfit of a setup (we were a few peeps playing specs and classes that were very uncommon, even frowned upon): at the time you needed a rating of 1850 to be able to buy/acquire certain gear. We had been grinding for days and hours, hovering close to that limit... one night, probably 1-2 am, we're all getting ready to calling it and we try one last push -- and we won a few games in a row and pushed above.

Most satisfying, amazing feeling of accomplishment maybe ever (#847595)

Chess, I suppose, has replaced that these days (#853488).
