I would love a career mode, like in the "Road to the Show" mode in MLB: The Show. In cricket, it would be you starting out as a 18 year-old, perhaps even starting out in the Under-20's or something like that. As your stats improve, you get called up to the State squad, and if you perform well enough there, you get into the national side.
But I'd even be happy enough with stats tracking of the international players. At minimum, we should start out with that player's official statistics, and as we play the game, they change. I would like to monitor the players number of 100's and 50's, number of innings, and [crucially] their average in all formats of the game: T20, ODI's and Tests. I salivate at the idea of bringing up a batmen's average if he is going through a slump, or show concern when his average slumps, or celebrate when he brings up his 30th Test century. Similarly for bowlers - let us see their bowling average, number of wickets in all formats, and their best figures in a Test/ODI/T20.
People love stats. It's what drives us. It's what the commentators always talk about. We love to see them change over time. We marvel at upward and downward trends - a "batting slump" or the "fastest player to take 50 wickets". Stats tracking would not only overwhelmingly enrich a cricket game, dramatically increasing it's replayability and depth, but it would make it real for humans. Please include it.
