They kept releasing patches they claimed would fix all the problems everyone but the developers claimed to be having, and then after the 4th patch was released, they shut down their forums so no one could post any additional problems. They said judge them as they were now, not what they were before. It still sucks. You could have an enemy rush up behind you and start attacking, and before you had time to turn around to face him, you'd be dead. They were auctioning off a terrified teenage girl as a sex slave in Buccaneer's Den, and you could hire a prostitute there, and if you used a drug you'd wake up in a bed with a male pirate there instead of her, indicating you got man raped. Things like that shouldn't be in the game at all. You had one dungeon which was the most horrible time consuming massive maze imaginable, you having to run back and forth looking for different color things to get through it, and it just ridiculously tedious. Not fun at all. The lag problems won't be an issue with modern computers, so no need to bring that up. The dialog and plot are lame. Eliminating the rest of my review, so its not too long to post. I'm sure you get the point.
Once you learn to master every faction, you can have a really enjoyable game. I suggest trying high energy maps like Angvir Maze. You have an option to play with Crusade balancing, which was tested by hordes of players and refined to be pretty good. To prevent tier 1 units from swarming, they made defensive structures stronger against them. I found some of the campaigns a lot of fun. Some lame ones you could just select all your units with CTRL A and then hit CTRL D to destroy them, then back at the menu had the ability to skip that mission. You could also use the cheatcode to skip the few lame ones.
