One of the areas for improvement that I see with MMOs is the area of making an MMO multiplatform. There’s a big opportunity for making a game more accessible (and therefore more likely to be attractive) by allowing some bits of it to be accessed by devices other than the main one used to play it; mobile devices being the main one I’m thinking of. The Mango update to Windows Phone 7 makes this possibility much more attainable for our game, with the addition of Sockets.
The main question that needs to be answered is “How much of the game should be accessible on a particular platform?” This is going to depend on the capabilities of the platform obviously. For WP7, it’s not reasonable to expect that the main part of the game where there are potentially hundreds of players running around with dozens or more mobs is going to doable.
What does make sense for a mobile device interface into the game then? The part of the game that isn’t the part mentioned above perhaps? Things like character tweaking, inventory management, purchasing/trading items, texturally interacting with other players, etc. Basically the areas of the game that aren’t hardware resource heavy and not real time critical.
Would having multiplatform capability make a spy genre MMO more interesting or more attractive? I’m very interested in hearing what people have to say about this.
