Comments: Pottery was not well written, first time my brother and I played, he destroyed by trading all his resources for 10+ cards (minus two, of course) every turn and then destroyed me with a large army.
Catapults only bouncing walls to a hand (sorry, MTG player) is annoying. They should destroy outright.
No max hand size adds a brilliant touch to the game. Until, of course, someone attacks you with 7 chariots and 4 swordsman after building a barracks. Then you cry. (luckily I always keep Archers. Always.)
Recommendations: When discarding, always discard face DOWN, this prevents card counters (like me) from getting an advantage, plus you can easily guess who has a small army that way.
Make sure you agree on whether cards in hand can be traded for real resources (i.e. a 3 Production card in your hand for 1 "real" Food)
Either have one person be the banker or count your resources while your opponent draws/discards. This shortens game time and helps insure an accurate count. I almost always screw up with the Pyramids.
Questions: Do the pyramids only add resources based on the plot they are on?
We don't modify at all when we play. Don't think it needs it.
Maybe a calculator for tracking resources would help though...
Pyramids are just 2 free resources of any type.
And yes, you should always be able to trade in 3 production for 1 food, regardless whether those production are in your hand or in actual production cards. I believe the rules say something about the bonus resource cards are treated EXACTLY as regular resources.
