Most of those issues that you listed are most likely going to be resolved with 0.6. I&#039;m not entirely sure about slopes, but I wouldn&#039;t be surprised if that was resolved as well. But even if it isn&#039;t, a few of those maps have already been converted by hex and he is capable of converting the rest. You can make a case for 04, 08, and 18 but these maps are getting ancient and it wouldn&#039;t be a big scandal if they were removed. Converted 29 and 20 play the same as the original sloped versions. I wouldn&#039;t expect anyone to just abandon maps without trying to work on them. In its current state, oda is a bit too rough to host IDL. However, after the release of 0.6, Odamex will be more than capable of supporting IDL. Now, whether or not it would be ideal to attempt a move from zd to oda so soon after the next release is not my call.
