6. New Co-op missions

It's great that Rockstar included some co-op missions in GTA 4's online game modes, but even a week after release we're ready for more. We wouldn't mind too much if they simply re-worked a few missions from the story, as long as we got more co-op action. Of course, some completely new missions designed from the ground-up for co-op play would be brilliant, especially if we're able to use properly customised characters.

5. Cameo appearances

This one is a bit out there in terms of it being highly unlikely, but imagine walking down the road in GTA 4 only to see a movie star. You've just mounted the pavement after going wide on a corner, smashed into a civilian and Samuel L Jackson's face is staring at you through the blood-smeared windscreen. We'd pay good money for that. If proper celebs are too much to ask for then we'd settle for new crazy characters that appear in the city, be it an off the wall busker, clever beggar or 'interesting' lady of the night.
