Diablo 3 and Sim City sucked the gaming out of me. Not sure if I'll ever recover.
seriously. there is your problem right there.
Time is definitely a problem as you get older.
Doubt you will find to many 25+ people that will REALLY complain about Bioshocks 11 hours of gameplay and zero replay.
But at the same time, what got you into gaming? what kind of game?
Are you telling me you can't find that experience again?
Cave story, or that recently linked Un-epic for metroidvanias? the cave. or any number of others.
Robot unicorn or the myriad of other flash games, many of which are pretty amazing. kingdom rush, to crush the castle, to epic battle fantasy, to puzzle and dragons, to plants vs zombies, to candy crush, etc. desktop gaming, handheld etc, has a ton of really fun games too.
And this is the kind of gaming we used to have on NES and atari.
what about those amazing games of the past you missed? did you own every system, or were you a nintendo kid that missed out on all the classic sega games? if so, go play the phantasy stars, and shining in the darkness series right now. Temple of elemental evil, planescape, beyond good and evil etc. GoG and steam are loaded. even wii/psn, etc have classic games.
Like minecraft?
Dwarf fortress, gnomeria, towns, or like any number of about 20+ clones of MC and DF that have been in kickstarter/alpha/beta recently.
Terraria, darkout, starbound, etc.
