Starcraft Battle Chest includes the original Starcraft game and its expansion set Broodwar, as well as complete strategy guides for the game. It's a great addition to the Starcraft Collection, and it's generally much cheaper to buy the Battle Chest than buy the original game and the expansion set separately.
Once you've installed both the original and expansion set from the Battle Chest, you'll find the game very enjoyable. It's fast paced and very exciting, and runs pretty fine even on slower machines. The graphics are great, and so is the gameplay. The campaigns are never boring since the storyline is cool. I get to control he heroes of the game and accomplish the mission, which can be pretty challenging.
I highly recommend the Starcraft Battle Chest, it's a great game. Even if you already have the original and expansion set, this will still be good collector's item.
Buy this! It's worth the price!
