In short: Godus is way less an actual game than it is a cow clicker, it's a free to play game at heart which they dare to charge you €19 for.
The "gameplay" consist of you clicking over and over and over again to let your people do the most basic tasks, it's tedious and not fun at all. Currently there is no AI, your people don't do stuff on their own. If you want them to e.g. build new houses you have to click on one of your existing houses to make them come out. Once you did that they move towards the closest plot, build there and then enter their new home and don't come out till you summon them again. Due to that the whole world feels empty and your people seem to be soulless.
You have some god powers like sculpting land which are fuel by belief which you have to collect manually by clicking on your peoples houses or later, a couple hours into the game, by clicking on settlements. Sculpting is not your only god power but it's the one you will use almost all the time to flatten land in the most tedious way possible. You have to click on a layer and hold the button down you you can push or pull that layer for an inch. That's it, if you want to sculpt more land you have to do this over and over again. It's simply not fun.
What's even worse is that, besides that, there isn't much to do in Godus. In theory there are twelve different ages (currently only two are implemented) to advance through, but those ages don't feel different. During the bronze age the only resource you need is people, once you have enough you advance to the bronze age where you don't need people but crops. So, the only difference between these two ages is that you build houses in the primitive and farms in the bronze age.
Oh, and speaking of resources. Whenever you get reach a certain amount of people/crops you get a technology card with you than have to unlock with resource cards. The problem here is how you get those resource cards, you find them in chests and it's completely random which one you get. You can find a chest in a forest and get rocks, you can find a chest in the mountains and get a candle. That's not just weired but also very annoying cos the amount of chests is limited and you can find resources you don't need. Lot's of people currently can't advance anymore cos they ran out of resources. They are forced to play multiplayer battles, which is not fun at all, against their friends (there is currently no lobby, if you don't know people that have Godus you have nobody to play against) cos resource cards can drop there too, but only for the winner.
Most core mechanics are flawed and need to be redesigned from scratch in oder to save this games. It sounds harsh, but atm Godus is not worth being called a game, not even beta, its more like a bedrock alpha. A framework with some basic but untested gameplay concepts in it.
What's even worse is the lack of communication and updates. It's been over 50 days now without a patch. All we got was a little youtube video with pretty much no helpful information in it at all. They said what they were planing to do but they neither talked specifics nor did they give us an ETA.
In addition to that Steam costumers are treated as second class costumers. Devs don't talk to you on the Steam forums and you have no access to the 22Cans which are private and for Kickstarter backers only, you can't even read them. Forget about being involved in the development process, you have not say in it and they don't even care to inform you about which decisions they made and why.
And don't get me started about Gems. They are used to either purchase resource cards or to speed up the horribly long building timers and 22Cans initially planed on selling them via an ingame shop. The only reason they didn't to that was because one of the alpha backers, which got the Early Access client before it was released on Steam, leaked that and we had a huge ♥♥♥♥♥torm within minutes.
The gems are still in and you need them if you want to progress at an acceptable pace, you just can't buy them anymore, at least not at the moment.
Godus is a prime example of what an Early Access game should NOT look like. 22Cans earned their place on may blacklist, maybe if they turn this around and step away from trying to force a mobile game down our throats this will change again. But, to be honest, I don't think that they can do that.Update 2013-12-13: 9 Weeks later
Early Access games are usually meant to be updated on a regular basis, they should evolve and the community should be part of that process. Well, that's the theory, a theory nobody told 22Cans about.
Godus is in a very early state (the current build represents maybe 15% of the promised content) but it hasn't received an update in 9 weeks. 22Cans is not a big company, I don't expect them to deliver a big update every week, but even rather small dev teams can update their games once a month. 22Cans doesn't bother to do that, there are no minor patches or hotfixes, they don't address their players' concerns in time (or at all).
The devs try to excuse this by saying that they are currently working on some major improvements (see their video update #34 on youtube), but even that statement is 6 weeks old by now and since then there has been nothing but silence.
At this point it becomes very hard to say anything positive about how 22Cans has handled Godus so far. And, from a pessimists point of view, the silence and lack of updates even suggests that either the devs aren't capable enough or that they released Godus way too early and they now have to redo lots of it.
