As someone with only low level computer skills, who used to think Imgur and Social Media were just for the under 30's I have some proposals, for a Simplified game, that only goes up to Renaissance. The beta would continue, as a home for those who know their PvP, from their PvE. But for those yet to try PvP, we need a place to learn. Somewhere without to BF, FF, DR, PB and others like them.
Having tried Industrial and Info age, Once, I have to say, I hate them. Industrial age is ugly and complicated, Info age is pretty, but complicated and I don't want modern stuff. I come here to get away from the modern world and all it's horrible problems, like nuclear weapons, Trump, Kim, the Kardashians, etc and all that modern stuff, like teens who think it is cool to be rude and nasty.
Once people have played for a bit, learnt some skills and feel ready for more of a challenge, then they could join the beta.
This would attract puzzlers and those who loved the TTG and gradually turn them into fighters.
Leaving the fighters to slug it out in the Beta, you could then stop worrying so much about 30 day rules and such like.
Those who join the Gamma, are your niche market, you are the only One making a decent game for us.
Your beta could have so many more Nuclear wars :) Without all the innocent civilians getting slaughtered and driven from the game. There would be a lot less meltdowns and whining. It would be nearly all Conans.
P.s. Can we have our own separate forum, so we can have the fun of working it all out, from scratch :))
