for worms armageddon custom maps could be made... rope race, proper, shopper etc. will these be introduced to xbox 360?

well? :o

hmmmm

I doubt it. As soon as MS gives users the power to create their own content (for 360 games in general), users won't purchase as much downloadable content (although they would sell more copies of some games). It would be nice to put custom maps on a USB drive and hook it up but it's not a standard supported by MS, so developers can't just add it. Apparently there is also very limited profile/save space for XBLA games, probably not enough to save your own maps. I know most users have gigabytes free on their 360 HD but for some reason, MS limits the profile space to kilobytes.

I think MS just want to make absolutely sure that there is no practical limit to the number of games you can buy from them.

surley the devs can make a few into the game as generated codes?

Allowing users to make their own maps would seriously take up some room. When worms XBLA was made, the 50 MB limit was still in effect. In order to have included that, they would have had to skimp on several other necessary areas. And putting new items into the game takes alot of time and effort. Whenever they make another one(if there is going to be one), it most likely have more features because of more room.

I don't know what this question means.
