In reality, more folks would reach Industrial (and beyond) if all times were reduced. The current times made sense several years ago but today there are 11 war ages (Iron-Digital). Someone new to the game has absolutely zero hope to reach for the stars (Space) and realistically no hope to reach Cold War. Not even a $1,000 will get there. Probably not even $10,000.
Everyone knows that the game gets fun at Industrial yet many will never experience it as they give up due to long upgrade times. Same is true for Atomic, many will never reach it due to all the long upgrade times despite Atomic being the best age in the game. There's no doubt this slog causes more people to cheat.
Decrease upgrade times and more folks will continue past Gunpowder, the player pool will increase, alliances will be more active/full, and more people will buy stuff.
It is so clear that this game could be so much more, so awesome... it's still not too late to do the right thing although that time is fast approaching. What do you have to lose at this point?
Heck, if BHG sold a decent instant Atomic package (one with, say, with Industrial defense and Global offense), many folks would purchase it and upgrade their offense and have fun. Don't focus on details (I figure max Atomic everything is not desired by most, and some work should be involved by the user). And if BHG made it clear to all how to easily use a 2nd alt account. Many would buy this.
