30 turns in 4 days is quite remarkable! So far I've found that casual games run
much faster than most ACT/AXT games, strangely enough.
The game comes with some scenarios designed to be used in MP, but I have no idea how balanced they are. The Apolyton PBEM tournament started on quite a silly map, where it was possible for the university to nerve-gas everyone to death by ~ 2050, I don't know if they fixed that or not
. It's not easy to balance these things.
And, as Stuntman19 points out, most of the difference between players is found in the first 60 turns (as I found out when Paul built WP and VW by '56..) Anything else just isn't Smac.
Perhaps you could have 4 or 6 players, starting in 2 unbreakable Pacts. That way they could leapfrog up the tech tree, finishing the game very early, while preserving all the elements of skill.
Or play tiny map vs the Spartans. Only a suggestion..
