I love forge and I believe that it has allowed for some awsome maps and gameplay ever since its release.
One of the main complaints I see is that all the maps are grey or look similar. Wouldn’t it be awsome if they allowed you to texture the surface of objects.
For example. A simple wall or building peice allows you to put grass/ice/snow/other? on its surface. This would allow people to make dynamic and realistic looking maps and we wouldn’t get the grey looking maps all the time. Maybe a little rolling grass hill as well?
Another thought is that these surfaces could make gernades act differntly. If a gernade lands in the grass or snow it won’t bounce like it does on hard surface. I believe this mechanic is already in the game however it is not really forgable.
