I gave Deus Ex a B+, so far the game is awesome. It has a dialogue system similar to mass effect's when speaking to people. It's not open world but has plenty of exploration and side quests within a unique cyberpunk futuristic setting for the city. Each mission gives you different ways to complete it depending on the approach you decide to tackle it with.
The Wii U version comes with a very handy interactive strategy guide within the game. The graphics are really good for the most part, except for characters faces. Some of the faces look like they belong in a ps2 game. Really, really low res textures on the faces. It makes the characters look weird because their outfits look damn good. All the outfits have high res textures, it makes the faces stand out with their ugly textures.
The gamepad is utilized very well in this game. They combined a very good method of being able to use the touchscreen or the analogue if you prefer for the menu and map functions. I think this is probably one of the best approaches a dev has taken with the gamepad.
The story so far is good, and I am enjoying the game a lot. There is a lot to like about this game but it doesn't come without its flaws. Overall it's a good game, B+ so far in my book.
