Food for thought:What if the old republic had survived?
Purly for the sake of arugment:
Lets say the empire never existed.
How would the galaxie look then?
Remember all thing's are purly speculation.
I personal think that if darth sidous and darth vadar where never born the galaxie would be corrupt ineffecent complacent weak unable to maintan order.
While they would be united in name there wouldnt be any unity.
Planets looking out for number uno with little to no regard to others.
Much like the un we arent really united but we find that helping eatchother is beneficial.
The Old Republic did
Incase you've forgotten, Palpatine became supreme chancellor of it.
