   Quick Question about Game Engines
  I'd like to know if an engine could run two "games" at once?I'm designing a combination RTS/FPS multiplayer game and I'd like the command actions of the RTS players to "drive" the AI of enemies in the FPS player's game. And vice versa, I'd like the actions of the FPS player's to be displayed in the RTS player's game? I've never seen this type of game and I know it sounds a bit strange, but mixed with other elements I think it'd work out nicely for the type of gameplay I'm envisioning.  I only ask because as far as I know, I've never seen it done. If anyone has seen this in a game could you please let me know which one?Thank you -Thomas   
  Yes, it'd have to be well made and probably customized heavily if from an existing engine but sure, it is possible. It's the implementation that's the killer part.   ;  SAVAGE: The Battle for Newerth Does something similar.  It shouldn't be that hard it is just different code paths for the different views and controls.   ;  It's nice to know that building the engine is possible, but it sounds like getting it done will be a challenge."It's the implementation that's the killer part." -any chance I could get you to elaborate?Thanks stonemetal, I'll look into that game.Thank you for your time, I don't know if it means anything to you but I gave you a good ratings.-Thomas   ;  The Half-life mod Natural Selection did something very much like that.   ;  Thank you for the link. It's good to know that sort of gameplay has been successfully achieved. :)Unfortunately it also means my idea isn't as original as I first thought. :(Thanks again to everyone,-Thomas;  Edit:Opps, I double clicked reply:-Thomas   ;  Although not quite what you are designing, Dungeon Keeper 2 allowed you to switch between a first-person and birds-eye perspective at will.  And of course there is always the ghost recon games for a bunch of multi-view stuff.
