| the neutrality all tiles available doesn't actually give all tiles available. |
Suralle... I think you are misinterpreting the neutral benefit. "All" tiles is a bit subjective... it's really all improvable tiles. ie: all tiles that could be improved via terraforming, etc are available as soon as you choose a neutral alignment. All the benefit does is prevent you from researching 2-3 planetary improvment items.
Still, it's a very useful benefit, considering you could have every improvable tile available long before mid-game instead of late mid-game.
The extra trade routes have been the difference between solvency and bankruptcy when my planets are upgrading enmasse.
Of course, the wonders of the Neutrality Learning Centers have been well documented.
I haven't tried playing good, or evil, so can't comment on their benefits, but Neutral works pretty well for me.
