A push with a new idea from me:
As most of the people I know play titles bought on steam, you could add a steam-integration using the steam web-API.
Then you could add a few variables like:
@steamlink@ - Link to the game in the steamstore
@timeplayed@ - time played the game, reffering to the steam user info
then users can create custom commands like !game with the output
"elPerstin is playing @game@ for @timeplayed@ hours. You can find the game here: @steamlink@"
Would be great if you could review the idea. no bot i know has this function implemented, so this would be a nice feature to get new (paying) users
