StarCraft Brood War Data MiningAuthor: Alberto Uriarte. Last update: 06-15-2015
If you want to do some data mining or machine learning on StraCraft Brood War, don't reinvent the wheel. This is a compendium of all the work done. Just remember to notify me (albertouri[at]drexel[dot]edu) if you do something to keep this web updated.
First of all you need some replays (game log files) to do your data mining. There are some websites where you can find replays from professional gamers (a.k.a. gosu). It's important to notice that if you want to analyze the replays using BWAPI, you would need replays played in the last version of StarCraft Brood War (1.16.1).
- [W1] GosuGamers. Since 04-14-2013 they aren't adding new replays. 7,930 replays.
- [W2] ICCup. Still active professional game server with regular tournaments.
- [W3] TeamLiquid. Professional community with regular tournaments.
- [W4] RepDepot. Replay repository with more than 56,600 replays (gosu and user). Currently OFFLINE
- [W5] Reps.Ru
- [W6] yaoyuan.com
- [W7] ygosu.com
- [W8] defiler.ru
- [W9] bwreplays.com. Compilation of all the previous sites
Downloading all the replays by hand it's a really time consuming task, you should use a crawler to automatize this process. Keep in mind that the same replay can be stored in different websites, so it's a good practice to check the hash of the replay to look for duplicates. Some replays could be corrupted.
- Broodwar Replay Scrappers. Developed by Gabriel Synnaeve in Python. It downloads replays from [W1], [W2] and [W3].
- Tutorial how to create your own crawler.
Once you gather a nice amount of replays, it's nice to offer your replay package to the research community to be able to reproduce your results and compare it with new approaches. The map of the replay is included inside each replay file.

Now is time to parser the replays. For this we have two options, parser the replay file or parser the BWAPI events/states. The first one we don't need to play the replay on StarCraft, but we only have the click commands of the players and we need to decode the binary replay files. Using BWAPI we can record all game events and all states of the units, even simulate the fog of war, but we need to play each replay in StarCraft.

After parsing the replays you will have a clean dataset ready to apply machine learning techniques. Each dataset has been created with some data mining in mind, so maybe they don't capture the information that you want or with the granularity you need. So feel free to create your own dataset using a replay analyzer.
