Definitely need more than a plus 1 to give to the upgrades thing and also to the idea for count down.
I love all the differfent options to improve your businesses. Achievements, upgrades, managers... very well thought out on that side of things :)
I am in the same boat as "The Omnipotent", I have gigs and gigs of games, a PS3, an Xbox, heaps of games on my phone and a million other things I should be doing. Instead, I sit here watching my screen until I can buy the next upgrade :P
I didn't think it could happen. But I have gotten bored of this game too. At level 19,000+... there is no challenge anymore. I've got a level 6,448 steel sword. It has 114,000+ attack, and ~48,000%+ for each stat. I have level ~1,800 callistite armour giving +28,000% to each stat and 330,000+ health and over 5k defense...
I am cleaving for damage in the tens of billions, even callisteks and golems at level 2,000 are dying single shot! Please Dev, put in more challening things!
