I want a gaming community wherein every month an old multiplayer server based game is revived and people compete for prizes. The problem with this is that it requires good connections to the corporate owners of those games, to get permission to ship the .exe with a simple hex edit changing the master server list host. Or even add game modes. The intent being donations for various charities too of course.
There's still an existing community for games like the original PC Red Faction, as crazy as that is. Perfectly fun games, just needs players and some names in game streaming to pick it up.
