Flow

Before the game

Persons can register for the matchmaking, becoming Users of our service
Users can connect their aoe2-profile with their account
Users can adjust their personal preferences regarding maps, ladders etc. in the settings.
Users can queue up for their settings or join a queue they see are the most people in, other recommendations
Users get informed of their match in their client with a pop-up, switching to the settings of the match
A Host is being decided randomly of all participating players.
Else, Users can set their preference in the settings if they like to be hosted more often.
Hosts create the game lobbies (until, we haven't found a way to automate that)
Lobby settings get verified as much as possible via aoe2.net matches API endpoint
Match starts

get basic game information/result from aoe2.net
download, parse and analyse recorded games
use results if recs are unavailable
- results when both players pick no team still show both winning, so recs would be best (aoe2.net)
create rating change
- with the recs analysation, we could even calculate a more precise rating change depending on how the game played out
- like a player that was dead in minute 13 and just stayed in the game until 1h25 because the person had a vill hidden in the corner should probably not get so much rating change as someone that was carrying all the people the whole game (just as an idea)
