They should be, or take down the features list and only display what you get when you pay for the game. You can't list a ton of features luring in a person and let them buy it to find out which ones are in the game and which ones aren't, that's absurd. There's only one excerpt on the feature page stating what will be forthcoming, which is:
Evolution
Xsyon is constantly evolving. During the Prelude, characters start off as simple hunters, gatherers and scavengers. As societies will advance new features will become available to the larger, more civilized tribes and towns. These features will include:
Animal taming and riding.
Player comfort levels that affect actions.
In game message boards and mail system.
Agriculture.
Cooking with player created created recipes.
Armor decoration and enhancement system which can indicate achievements and status.
New content including armor sets, weapons, buildings and creatures.
Religion.
Join us in the Xsyon Forums for discussions of other potential unique features that we plan to develop and try out.
The rest , as laid out, is advertised as what's in the game. If you look at a products feature page that has no actual physical box, that's the marketable ploy of the product that you're selling. Given that you actually get no physical copy, that feature list is one in the same of what you would/should be seeing on the game box should there actually be one. If you bought a game in a retail store and it listed a bunch of features that you then logged in to find out weren't there, it would be the exact same scenario and that is false advertising. You can't claim a product has 'x' feature and then sell it as such when it clearly does not. You also can't rely on a fall back of 'oh, but it's somewhere on our forums saying those features aren't actually in game'. (( Which is funny because they DON'T even own up to that, or when they're actually going to work on putting them in.) The company needs to give their head a smack and reverse the process. What's in game should be on the features page and what's planned should be on the forums. Instead they lure people in with ideals that don't exist and they don't even explain on the forums when the actual features WILL be in. It's not a hard concept, if you don't have what you're selling, you don't adverstise that you do.
