I was thinking: HeatMap
Ok lets make it work:
Use a mssql job to save every online player every 60sec
- > 10 Users online
- - > 60 query's /min.
- - - > 3600 query's /hour
- - - - > 86.400 query's /daily
if you "think" that that's low => No problem
but if you have 100 users online ?
final result?
Its possible to make, but is it worth ?
