This is for those of you who have made multiplayer games, as in online/networked games, not local multiplayer. I know this is one of those "Well, do YOU want it to be XYZ?" questions, but hear me out. Not all games are worth multiplayer. I'm working on an 3D person Action/Adventure project right now and the magic system I've created is kinda cool (I think). I often wonder if people would feel the same if I introduced lag, hackers, and high ping into the mix. What helps you come to the conclusion that your game idea is worthy of the effort to make it online multiplayer?
