What engine are you planning on using? At work, with Unity, I use seperate files. I create the rig and save it as the model name, for example, "ENEMY1.fbx", then each animation I do, I save it as "ENEMY1@WALK.fbx" "ENEMY1@RUN.fbx". I find it easier than importing all anims into 1 scene. Though, if anyone else has a reason…
