Technical Performance

Blizzard has optimized this process over the last decade, but it remains inconsistent.

  • On High-End PCs: It is a blink-and-you-miss-it affair.
  • On Budget PCs: It is a bottleneck. The worst offender is the "Syncing Data" phase that sometimes follows, which depends heavily on internet connection stability to Blizzard’s servers. If the connection hiccups here, the match is canceled, wasting the player's time.

4. Preprocessing steps

  • Normalize timestamps: convert to seconds from match start; align to fixed sampling rate if needed.
  • Standardize IDs: map raw unit/building IDs to canonical unit names and categories (worker, combat, air, ground, spellcaster).
  • Handle variable match lengths: truncate or pad timelines; use relative time windows (e.g., first 6 minutes).
  • De-noise actions: collapse redundant actions (e.g., queued orders), filter spectator artifacts.
  • Coordinate normalization: transform map coordinates to a consistent frame (e.g., normalize to [0,1]) and optionally rotate/flip for symmetry augmentation.
  • Missing data: decide imputation (zeros, forward-fill) or mask positions/timelines.

1. Replay Data Extraction (for analysis / ML)

SC2 replays (.SC2Replay) are not raw logs—they record player actions and game state changes. To extract structured data:

  • Tools:
    • sc2reader (Python) – easy, but slower for large batches.
    • python-sc2 + replay parser – faster, used in bot development.
    • SC2ReplayPack / SC2EGSet (from DeepMind) – preprocessed pro replays.
  • Key data to extract:
    • Timestamps, actions (move, attack, train, build, research)
    • Unit positions, health, resources, supply
    • Upgrade progress, tech tree, worker counts
    • Map name, race, outcome, MMR
  • Challenges:
    • Replays don’t contain full continuous state—only changes.
    • Map geometry must be reconstructed from map file or precomputed.
    • Units can be hidden by fog of war (depending on perspective).
