Really, I almost bought the game when it came out, but the store page on release was damn misleading.
To begin with, they mentioned there were maps between 100-400 sq kms, when all they had at the moment was Colorado. They mentioned that you can kill zombies to gain experience and level your skills up, when skills were not implemented in the game yet. They mentioned there was driving, when there wasn't. And now that they updated the page so that it's more in touch with how the game is, they're claiming that people have misinterpreted the store page. Misinterpretation only works when someone is being vague, or uses double meanings: there's no way to interpret maps as one map, no way to interpret upgrade your skills as there being no way to influence your skills in game at the moment, and there was no way to know, from looking at the steam store page at the time, that all these features were not present in the game, but were planned for it. And no, you cannot put the burden of the research on consumers, since we've gone through this before as a species, and put down rules on fraud. Advertising can embellish things, but it cannot outright lie about what is in your product.
Other than that, from what I've seen, they may not call it an alpha or a beta, but it is an alpha in spirit. The interface has unimplemented features showing, which can be expected to be put in within the next year, in game reflections are handled by duplicating objects, and the game has pretty high system requirements for how it looks and plays.
I can't trust the Sergei Titov after this, especially when his response to this is to act like none of this is his fault, that the people complaining about the game are a vocal minority. It seems all discussion about the game has been about the controversy, not about how to play it; given that the game doesn't come with a tutorial, I'd expect there to be people that head to forums to ask about things.
