The way the titles are done in the trailer is really good.
The screenshots look good but the gameplay graphics I didn't like as much, baring in mind that it is of course still in development.
Also considering it's only just been officially announced, I hope it wont be a rush to get it in by late 2014, as I doubt they'll want to push the release back considering the whole Aliens: Colonial Marines thing.
I also don't know if it'll be a great success if there is only going to be 1 alien. Yes, it's a horror, and is (in theory) going to be like the original, and all that, but realistically I don't presume I'm going to be that scared playing, when it's obvious I'll survive until the end, the alien will probably seem dead the re-appear, all other crew will die (possibly one survives). That is going mostly off film logic, as I don't have much horror game experience.
Just a pet peeve of mine too, why do so many action (in this case more horror) hero's have to have children which grow up to manage get into the exact same situations, if not exceeding (usually in films).
