Cons
Con Bad visual design
Obviously this is an open soruce project so nobody expects AAA level gfx but this one looks exceptionaly bad. Some of the weapon effects are hideous to look at. Simple things like UI buttons and color scheme seem to be visually out of sync with the way unit models and the map terrrain look.
It seems like a mishmash of visual styles which is probably a result of many different contributors of varreying skill levels.
There definately are visually consistent and pelasant ot look at open source games so The visual design of the game needs to have some sort of strcut guidline or rely primarily on the taste of a single individual from the ZK team.
Con Flat balance
The economy is very close to a Total Annihilation economy (despite all the changes they introduced) but the unit balance resembles games with harder unit counters like Warcraft and Starcraft. In Blizard games, there are different ways to limit what unit type or kind you can build at any stage of the game, like tech structures which the opponnet can scout.
In Zero - K this is not the case since there are no tech buildigns focusing the player on a certain unit type which can be scouted. You can make all units at all times. The gameplay design feels amateur and not thought through From the broadest perspective. It also manages to miss the advantages of the Spring engine and mixes the need to micromanage units that counter each other with big Area of Effect Weapons.
