So a friend of mine and myself have been working on a game we came up with for a while, and its been coming along. We have been keeping it quiet because we felt it was a really good idea, and really liked where it was going. However, just yesterday I was on IndieDB, and I saw a game pop up on the banner, and it looked really interesting (meaning it looked a lot like the game we were making). I took a look at it, and it was really awesome, and it was everything we are doing and more. Not only that, but they already have a playable game that is for sale on Desura, and just launched a Kickstarter to "finish it".
As amazing as the game looks, it was like a punch in the heart because it seriously demotivated me from continuing my project. I don't need to have an original concept (if that even exists anymore) but I don't really want to make a game that is basically this other game, only they have some more features that would be everything I wanted this game to become.
What would you do in this situation? Has anyone had this experience? If so, what was the outcome?
EDIT: Interestingly, I came across this gamasutra post that was an interesting read on the subject:
