It's a shame Pocket UFO never was picked up in an official manner. It's a perfect copy of the original (being that well, it is the original), with a new UI optimized for touch screen. So at least it feels like real deal.
To me, this new port looks like amateur hour all over (which is probably because it is), as if they wanted to make X-Com with a tile swap. It also screams rip-off as much as any other gameloft game does, more so because all the elements are kept nearly exactly the same. Maybe there are more differences underneath, but something like Xenonauts would be better representative of what I imagine a X-Com clone to look like.
If you missed the original, there's no reason why you can't play it, if you wanted to. This game will not replace it, only offer an imitation of it. Maybe that's enough, but it's not the original X-com that everyone loves and cherished.
