This must be a nostalgia game. The textures might be higher quality, but I didn't see anything in that trailer that sets this game apart from Quake 2, half life, or other 3d shooters from the 90's. Without knowing it's a remake, I immediately compared it to other games made in the 90's.
I often praise older games for their focus on story telling and game mechanics. A lot of newer games use graphics as their crutch selling point, without actually making an enjoyable game. Sadly, that preview showcased only the updated graphics, which aren't that impressive by today's standards.
