well, the data files are basically XML. The problem has basically nothing to do w/ the wad files.

The problems stem from things like UI, data integrity, etc. There are many, many subtle issues that make it a lot more difficult than it may seem from the outside. This is why we had to cut this feature from the original release, despite how much we wanted to offer it.

Yes, these issues are surmountable, but they will take a large amount of development effort that we just can't afford. We're hoping that LOL 2 (quite a ways off) will allow for modability, but we'll have to see. And we're hoping that we can find an affordable way to patch a custom map feature into LOL 1. But when I'm forced to decide between catering to the vast majority of users by having a better core game or building in modability for the minority of users that will take advantage of that at the expense of having a better core game, I'm always going to opt for having a better core game... =)
