And the effective protection of in-game NAP’s, which allows for massive intra-family planet swaps, so you can do a huge con build on hundreds of planets, without the risk of attacks.
With ‘unofficial’ NAP’s you never know who’s gonna stab you in the back, but the in game ones are secure.
I like the ingame NAP’s because is also secures wars etc, hence, the science delay should to be addressed.
