Tip #3: Building cities around greenery does only give you Victory Points at the end of the game. As far as I know In solo game there's no notion of Victory Points. The city will increase your income, raise extra money if placed adjacent to ocean but there's no benefit coming from placing it next to greenery tile in solo game.
Absolutely right. Commerical District is so useful early rounds, won in solo mode just barely because I built commercial district after cupola city then build greeneries from those two tiles to win!
I assume you mean the map? Its the expansion Hellas & Elysium that gets you 2 new maps to play on, changes a lot. You can check it out more in my expansions video here: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EVDjaHS19YA.html
