Unlike a lot of other FROM Software titles, Armored Core 6 needs to be launched from its working directory. Unfortunately, so does Mod Engine 2. This means that you're pretty much forced to have both Mod Engine 2 and Armored Core 6 in the same folder, so a multi-game config that has Mod Engine 2 in a different folder currently isn't feasible.
