Deus Ex: The Fall looks deceptively like Human Revolution. However, closer examination and actually playing the game quickly reveals it is no more than a touchscreen port impostor made with the Unity engine. It does not look as good, there does not seem to be a physics engine, and the gameplay does not have all the features you would expect when coming from DX:HR.
Not so nice is the lack of buttons on touch devices, which leads to heavily simplified interfaces in games. In The Fall, this is noticeable mainly from the missing ability to aim down sights and jump -- things you would expect a first person shooter to have these days. Also, upon the PC release, the game did not have rebindable keys. They patched that in six months later, which is quite a long time and it could be said that it was too little, too late.
While they were at it, they also removed the horrible zoom in/out effect that was supposed to imitate recoil or something. I am happy I did not have to experience that - an upside of playing games long after their release. Also, surprisingly enough, the game has quicksaving, although there is only one (1) saveslot. Thus one has to be careful when pressing the button lest an unwanted game state gets saved.
I do not see the word 'episode' on the game's Steam store page. I got it as a part of the Humble Square Enix Bundle, though, so I don't feel exactly cheated there. But they could still mention it is not a full game you are buying.
I was also somewhat bothered by how the protagonist, Ben Saxon, uses mostly the same animations in dialogues as Jensen but then sometimes jumps into one only NPCs in Human Revolution used. Not a huge issue, just something I did not expect to see and what slightly irked me.
The other problem is how there are no stores in the game, for you carry the store with you. Need an EMP grenade? Simply open your inventory and buy one! I guess the mobile version had microtransactions in it. The things publishers do in their greediness...
I guess Deus Ex: The Fall tickles that need for more Deus Ex. And that is why I mostly liked playing it. By trying really hard, you can convince yourself it is Human Revolution you are playing. Heck, the game even uses the same soundtrack (I think the club track is the only new one).
I hope the next DX will be a proper game.
