Game Making is without a doubt one of the greatest experiences I have ever had in the life -- but to this date I have only completed 1 game (and discarded at least 50 games). The most common reason why this continues to happen (and I'm sure that I'm not alone here) is because during the design phase of the game I am currently making I suddenly decide "Hey, I've got an idea'. How often does anyone else do this? Neglect their current project to satisfy their needs to unleash their creativity into a new one? Now, normally new ideas are good. The reason they're not in this case is because you can end up with 5 different projects going at the same time which almost always results in 'burn out'. What I'm meaning by that is you have mentally exhausted yourself by trying to program and bug fix the vast amount of projects that you've started and your brain simply decides that what you are doing is no longer fun. As the cycle goes I typically delete the projects from my hard drive or simply neglect them to the netherworld. So, what are your guys experiences with trying to say no to your new ideas?

That's not a Game Maker's problem alone... Almost every artist (musician, visual artist, designer, architect, etc) passes through that phase at some point... The tsunami of ideias phase is something natural, you just have to deal with it and even when you have new ideias, the best you can do is stick to your current project 'till you finish it, maybe write down anything new that comes to your mind, or, if you feel up to it (and this needs more practice to do the right way), you can adapt your new ideia, in a way that you can still add it to your current project without having to start a new one from scratch... If there's one thing I learned from my path as an artist, is this: Enjoy that phase and take the most out of it, because when that phase is over, there's one thing that is very likely to happen to you: Artist's Block! And that is the complete opposite of what you're going through, so... Is not too good to handle... It is too bad... lol Very best of luck to you ;) Hope I helped in any way...

Whenever I have an idea, I try to add it to the game I'm working on. If I have another "great" idea I'd rather work on than the current project, it just means my previous idea wasn't good enough and it actually wasn't worth continuing.
