Collecting replays for #SkillCraftCa SC2 expertise study

We are researchers at the Cognitive Science Lab at SFU conducting a large-scale study on the development of expertise in SC2. This is done by taking replay files and measuring key variables such as Perception Action Cycles.

See here for a detailed discussion of SC2 in cognitive science research. We have also been featured on the Daily Planet.

Thanks to the online community, we received over 4400 replay files from players during our first data collection period. During this first collection period, we asked players to submit a single replay file along with his or her respective in-game ranking. Here are some interesting findings from the data so far!

For the current data collection period, we are aiming for a more accurate picture of skill development by measuring skill development at a more individual level. To achieve this we are looking for players who have kept a large collection (300 or more) of personal replay files.

We need your help in collecting these replays. Please spread the word and encourage players to submit replay files to
