From a thing I said two years ago: "Exporting games down to stats per millisecond. Stats I'd want: all the obvious stuff, like gold, KDAs, minion kills, items: but possibly more interesting would be HP per millisecond, and any secondary stats as well. Ability cooldowns. Ward expenditure. "Could possibly do something interesting for positioning, but I'm not sure how to express that. X,Y coords? That would be enough; it'd be hard to consume, but that's what data processing is for. Clicks and pings would also be worth dumping." I think you could get a lot of coarse-grained positioning data from the minimap, and possibly coarse-grained HP snapshots from spectator mode. You could definitely get ultimate/summoner spell expenditures from snapshots, too. I really do expect interesting data to come out of analyzing the spatial layout of the teams.
