I would build nuclear power station and nuclear bombs as first priority or else US will come to bring "democracy" to my country LOL.

Being dictator with "lolyal" army is not that good because you will have to please that army and be more concerned about your own survival than having fun, If I was someone with army of robots whom i can control in any way I want that would be better thing.
But in that case I woud not a dictator but God


If I was in that position there is probably too much to describe in few sentences on what society I woud try to build and how to spend my time for fun.

For start I woud add real sex education starting in the kindergarten with purpose to teach children how to properly please each other and then make sex national sport making is custom to end every competition or meeting with orgy.
I would build all society around sexual pleasure and any other pleasure in general as reward for work.

Guro styled consequences would be applicable to the opposition and those who refuse to follow my rules. as there woud be no prisons of any kind and criminals woud be just getting some amount of torture/humiliation but In general I woud more stick to observing than actively participating except when doing show on TV.
