What makes you think "I'll make a full game out of this?"
I've always adored (from a distance) gamejams as a place where lots of cool and innovative games are born. But I didn't dig too much into it, and was surprised that lots of the titles that came from jams most of the time did not even score that good.
This time I joined LD53 as my first jam, and of course after getting some encouraging comments like "you should make a full release out of this" I got into thinking - is my game idea worth continuing working on?..
So. What is a "marker" for you? Is it getting a top-10-ish place in the end? Not being able to stop thinking about enhancing jam build? Encouraging comments? Just having free time and nothing else to do?
