It has come to my attention that a small number of people don't have BI or ALX, but would still like to try out the mod.
Adding RTW compatibility in itself isn't very complicated, but it will somewhat increase the workload / testing slightly. That doesn't mean it'll slow down the release of a patch; it means I won't bother testing on RTW and it probably won't be stable at all, resulting in frequent crashes.
All in all though, at least you can somewhat play it with only RTW 1.5. What are your thoughts on the matter?
