I wish that the ‘Earth’ story, could have been better, but maybe not.. for the wrench faction.

for the other Good factions,.. I wish that the Earth could have not had to pass away.

there weren’t alternate planetary events logs to suggest that the Earth people had all gone corrupted and turned into bad people, from the meta nationalists and Bad idiocracy individuals who could have made the Earth people to become bad people, to have to deserve going the way they did.

I would have liked to have seen my changing of their Eco policies towards more Ecologically helpful values, resulting in them maybe saving themselves (from I guess, game programming),… but that didn’t happen.

So unfortunately, Ecological Collapse and paralleling the “2012” movie,? was the only way that dealing with the Earth, was made to be like. Still,? I remember seeing the “ready player one” movie, where goals to reach, came at non thought ways of getting to them.

Can you all make the Earth game to be ‘better off’ somehow, in an upgrade to come for the game? That would be great.

Great for space enthusiasts

I’m writing a good review for this one. I think this is an awesome game. For a Sci-Fi nerd like me, this brings games to a whole new level. It’s hard at first, figuring it out, but after a while you get used to it. The graphics are top-quality, the physics on the gas and biosphere are so realistic, and the feature where you can look at your world from every angle is really good. I just wish it was easier to earn GP. But other than that, it’s really good.
Just watch the time- it’s easy to lose track of it on this one!

I wish that the ‘Earth’ game, was only bad to play,… if one played by the wrench faction, instead.

for the other Good factions,.. I wish that the Earth could be less fateful, and were found more towards farming and recycling still, … for more hopeful outcomes.

but having to cope with an alleged Eerie world, supposed of where mostly all had gone off into non farming and maybe costly abandons, mostly supposedly,… whom all maybe had gone some, with sects for idiocracies,?… and the rest, with corrupted meta nationalists who mostly, ‘had’ allegedly, totally departed into bleak ends?,.. consuming all plants seemingly to eat also,… and to watch all them disappear or pass away later, ?…

is not good, and is unfortunately, the only way to face, ‘playing’,? the Earth game. Can you all make the Earth game to be ‘better off’ somehow? That would be great.

bit unfair

The ads don't even work properly as You watch a video for free GP and the ad doesn't even exit properly, so doesn't register anything! sort it out!

Native Village chance problem

I absolutely love the game I’ve terraformed many planets yeah sometimes bad things happen but I get through but when I got a native planet I had no idea on what to do. Natives kept dying, missions failed over and over. I even got 50% happiness on a village with over 1 million people but it went down to 17% because a villager killed a human but I let it go but the natives were still mad and a meteorite came in and made the water 1.0 to .34 an enormous increase. Also renaissance was 95% success rate and went down to 16%! Why so low also I had to kill so many native villages because I had no idea what to do so I researched earlier today and there was things I had no idea of like needing a Shield for natives and needing 100% familiarity and at least 64% happiness. 64%? Sorry but that’s not happening with what we have but maybe they shouldn’t attack my city and next time it’s war for them
