Battlecraft is probably one of the simplest games on Starcraft 2, yet it is one of the best. The rules are simple: Kill the opposing 2 players with counters. You gain or lose points when you win/die, and those points count towards your score (F-D-C-B-A-*-**-***-[crown]). I'm currently an A, so I am high on the scores.
When you pay for a unit, you get more than one unit. It's all very balanced, and there are little to no cheap combinations. This
The games go by fast, typically 2-5 minutes but with higher rank games it can get up to 30 minutes. For a quick bit of fun, just hop into one game and play!
I give this game an 10/10, I've played it since Starcraft 2's release and still love it. I probably have over 1000 games, and it never gets old. Make sure to check this out!
