I really miss working on my game hobby projects but realistically don't have the time right now for hours each day what with work and other hobbies. My past projects were all big, ambitious games like an RTS, a driving game/simulator, etc... a whole day's work as I used to do and maybe you refactored your sprite class or improved your level editor.
If you wanted just to be able to throw games together really fast and spend the minimum time on anything that isn't gameplay, what would you do? I'm leaving this open as regards game style, technology/languages, platform... if you wanted every minute to count and you wanted to see a playable game almost from the very start where every hour's work you can see a tangible output...
(I'm a professional developer with a background in games, graphics and business coding so I like to think I'm fairly competent)
