Now to things I think could be improved -
Tech tree - well what can I say - just make it more obvious which techs go to which techs, some overlap, there is a very unorganized feel to it
Civilopedia - just get the entries in there, they don't have to be pretty or even have hypelinks I just want to be able to know the enemies strengs/weaknesses before I decide on a strategy (in other word I don't want to get slaughtered unexpectedly

)
Units - NLF infantry are sometimes invislible when they are attacked/attaking, Huey attack is VERY hard to see i had to squint just to see the tiny white flicker also the death is kinda wierd (except for one angle it's just a tiny white explosion/spot), I don't know if the USA is ever able to create ships but I hope so (I'm not knowlegable of Vietnamese history so ignore if it's historically correct), are there invisible units? my units seem to be attacked via ZOC yet i don't see enemies.
Scenario information - the opening box (aka scenario information) should be updated, now it say the US has just discovered farming, irrigation etc...
