Which 10 archer player and where? I'd sure like to see what spamming Archers can do on Deity. Also I don't play GoTM games for two reasons:
1) I am not ready for Deity yet.
2) They don't allow you to use CQUI and that's a deal-breaker for me.
Last but not least, how can you rate something when you yourself cannot explain EXACTLY what a perfect example of that something is? That's contradicting yourself.
I can tell you the result of 10/10, but to achieve it I think maybe I shall say too much. You shall try yourself.
Consider you're playing a normal Civ, under GOTM rules that you cannot replay turns.
Say it blank civ, with no UU,UA or UB.
what a 10/10 opening look like
By 100T
RV: Finished
DV: Finished
CV: Only a few turns to go
SV:
City Number: >25
Science: >300 Per turn, Finished Industrialization and Banking, and maybe something more like Printing and SciMeth
Culture: >200 Per turn, Finished Civic Engineering
Wonder: Finished Great Zimbabwe, with >15 Campuses and Hub/Harbor.
I think this is what a perfect opening look like.
You know, with strong CIvs like Aztec, it is common to finish SV around T120~130.
For blank Civs, <140T SV is 10/10.
That is what you get if you want to talk about a perfect example.
Considering people make mistakes, a 7/10 opening seems more reasonable. (Baseline opening for blank Civ)
By 100T
City Number: ~15
Science: ~120 Per turn, Finished Banking and Cartography
Culture: ~100 Per turn, Finished Exploration and Guilds.
These are based on blank Civs. If you're playing something strong, such as Macedon, pls replace the 100T to 85~90T, that's where you're at.
Also, certainly I think around T100 is not "opening", but absolutely "mid-late" game instead since most games last fewer than 150 turns if you want to play domination.
I attach one of my Macedon savings. That was the first time I played with that Civ(so absolutely I made lots of mistakes), also I lost tens of turns at the beginning, so I consider it as a 4/10 opening
