One of the most powerful religions is Andeanism, mostly because it is one of the
few religions that offer science bonus on the
temple (not just on the monestary, which comes later and goes obsolete at Modern Physics). IIRC the only other religion to offer that bonus is Bahai, which comes much later.
If you own a tile, even if it is ocean, you can connect your cities over it. If the ocean is narrow (and you don't have RCS on), you can often connect to a neighboring continent via a well placed coastal city. The effect is really strong on maps without sea tiles.
Edit: If you
manage to reach the TH era
, make sure you have graphite. Until the beginning of TH, graphite is not at all an important ressource, only needed for pencils (which you can do without), and even then lead is a viable alternative. And graphite is
extremely hard to come by (stone and coal in the city vicinity), so until TH there is usually no reason to bother.
But in TH, the following ressources require graphite:
- Graphene
- Liquid Metal Wares
- Shockwave Engines
- Novus Chemicals
- Levitation Generators
- Superstrong Alloys
- Cybernetic Chloroplasts (sp?)
- Nanogenerators
- Nanobots
- Nanoactuators
- Digitized Membrane (via Antropomorphics Lab)
You might just call TH the Graphite Age.
