/vr/ - Retro Games

I'm not trying to hijack the thread and turn it into a discussion of other turn-based strategies (or role-playing games for that matter, sorry M&M fans) but I'm curious to know why has HoMM community survived for so long, especially when compared to the crowd who played Age of Wonders, King's Bounty or Disciples. How come that there are no generals for them and the only reliable place I can discuss Disciples II or Age of Wonders is here?

Is it the multiplayer, the map generator, the overall gameplay loop or something else (or all of it combined) that made this installment of HoMM an evergreen game?

Also, what did the other TBS games do better than HoMM?
