Yeah, Time Machines are a pain in the ass to get the achievement for. I'm at 91 and the next one is going to cost over 41 trillion... 100 Time Machines is the last normal achievement I need too.
At this point it's not even worth it to leave the game idle anymore. I get more cookies with a single Lucky! golden cookie (currently maxed out at around 1.2 trillion each time) than I make in half an hour of idling... and a golden cookie spawns every 1-4 minutes (I think). I just want to play some SMT4 and Luigi's Mansion damnit. ;_;
