Downloadable content is one of the many double-edged swords of modern gaming: on one hand, it's awesome that developers can send new missions, playable characters and whatnot to gamers over the Internet for a nominal fee, but on the other hand, too often are devs evidently holding back material they made for the original game in order to part gamers with even more cash beyond the (usually exorbitant) price of the game itself. Then there's on-disc DLC, which is another blood-boiling matter altogether. But there are some DLCs gamers would just jump at the chance to throw their money at if developers were smart enough to realise it: while most of us can't bring ourselves to part with £12 for four new CoD maps, or 200 Microsoft points for that ridiculous Oblivion horse armour, these 13 potential DLCs would have gamers reaching for their wallets immediately, and would prove that downloadable content really can improve the gaming experience. Sure, not all of these prospective additions are especially realistic, but then, that's the whole point: if these developers really pushed the boat out and went the extra mile to make something of value that gamers really wanted, then they might be more inclined to say, "Shut up and take my money!"
