Greetings,
Having played a few 4X games, here is my take from 1 to 5 of the ones I know most:
MOO2 SEIV GalCiv2
Trading 2 4 5
Space combat (tactic) 3 5 1
Graphics 2 2 5
Tech tree 3 5 3
Complexity 2 5 2
Strategy 3 5 4
Races 3 4 3
AI 2 3 4
Enjoyability 4 4 3 (Here, MOO2 was the first, if it would be today, i think it would be 2)
Espionage 3 5 2
Bugs 2 4 3
Modding 0 5 5
Interface 2 4 4
Economy 4 4 4
Governors 0 5 2 (However, SEIV governors are quite dumbs too, but there are a lot more)
Until I see the next two other patches, I don't mind about the bugs. They have quite a complicated software engine with many parts and they have to deal with a great deal of different hardware and operating systems implementations. If they can work out 80% of the bugs in the next 2 patches, they will have done a good job.
Frankly, I thought Galciv2 would be a better SEIV Gold. Our friends, makers of Galciv2, should work on the next version to add some more complexity to the game (Carriers, mine, satellites, tactical combat, events, biggest tech tree). Don't take me wrong. it is a nice game, but it lacks some polishing. I really wish they will make tons of money to work on another verion or expansions sets that will make that game really the #1. Their "no copy protection" is a great plus for me and it is why I support their game and efforts. It is sure that I'll buy any expansion or other version (even if I prefer SEIV) to support their efforts to make it better.
I think they are on the right path.
Thank you
