It would be great if RPG In A Box 2.0 could contain option to create multiple animations for hit, death etc and allow the game to randomly choose from them during gameplay. This would allow more polished look for the games we create. For example, if you have one generic enemy model that you kill, they would not always have same animation playing when they die. Or if you hit an enemy, they could look like reacting differently to your hits each time.

You can already do that. You can either set up a timer that automatically changes animations into their other versions or (the better way) make it so that when an enemy gets hit, or dies etc, a script rolls a random number and depending on the number, you can change animations.
