I still play Battlecry 2 and 3 with my friends. You just can’t top these. They’re the pinnacle of the RTS genre. deepruntramp, WBC2 comes with an excellent foldout cheat sheet that details what every hero will be able to do. It lists all the spell schools and abilities and stats. It’s really a brilliant foldout that I used to read constantly while I was playing the game.
Some heroes that I would recommend: Human merchant (make your units really really cheap to build, but keep him away from combat!), undead necromancer (be a walking army generator, just summon undead anywhere on the map and upgrade them), and all the traditional heroes for Elves and Fey and Dwarves.
I just love these games so much. Another tip: You can do infinite queues, so you can be human for example, and build a basic barracks type building and produce pikeman and archers, and put it on infinite queue. If you want twice the amount of pikeman than archers, build two pikemen, one archer, and put on infinite queue. If you want equal amounts, put one of each. It works beautifully.
Another tip: For buildings that produce units, you can set their “attitude” which sets the units attitude when it gets produced. So for example, the building that produces Unicorns that can heal your hero? Just put the building on the attitude “Magical Guardian” and specify your Hero as the target. That way, any unicorns you produce in that building will automatically chase your hero around and help in his battles, and will automatically heal him when he’s injured. You can do this with any unit in the game, or any building.
Another tip: No matter who your hero, try to get a little bit of magic so you can get the spell which allows you to produce some basic workers right away. So if you can summon a grunt worker, you can put him to work in the mines. So right away, you start the game, summon some workers, and put them in the mines. That way your resources start coming in really fast.
That’s it from the top of my head for now, but one of my friends who recently moved to New York called and said he really missed playing games with us, and wants to regularly play Warlords Battlecry 3 again, so I’ll probably be playing the game again regularly soon. I’ll come back and post some advice if I think of any.
