3. Mass Effect 4
There are some games whose hype and potential defies words or description - mostly because no two Mass Effect fans can agree on anything coming out the third game's finale. Some absolutely despise the way things wrapped up, others think the Extended Cut sorted that out nicely, more point to the DLC as the place for all the missing answers to all those questions - and the rest of us simply anxious to see what happens next. So far Bioware have been fairly tight-lipped on the whole thing -
save for a leak that let the cat out the bag and got everyone speculating just how much therein was true. For E3 though, we need to see some gameplay footage, simple as. All the descriptions of the game have contained elements of mining, customisation in everything from your ship and armour to the drivable Mako, alongside an all-new plot that puts you slap-bang in the middle of an all-new galaxy-wide conflict. Please Bioware, don't screw this one up.
