I basically have two playable game prototypes but for some reason when I'm at this stage of development on a game my mind starts thinking about new game ideas and I can get sidetracked fleshing out new ideas. I know it's not a bad thing to have multiple projects going on but I don't want projects that are pretty far along to fall by the by the wayside because something new and shiny looks grabs my attention.
Does anyone else run into this and how do you stay on track with finishing a game project?
