Recently Stardew Valley celebrated it's one year anniversary and developer ConcernedApe wrote about that and the games long journey to launch. It's a really interesting read and something I recommend you check out.
"Today marks the 1-year anniversary of the release of Stardew Valley.
In some ways, it’s hard to believe that an entire year has already gone by since launch. Yet, at the same time, it’s been the longest year of my life. It’s felt long because I’ve done so much in the last 12 months:
-Game came out
-Released many patches to fix bugs and tweak gameplay
-Dozens of interviews
-Answered thousands of messages/emails
-Provided personal troubleshooting and technical support
-Made many Business/Merchandise deals
-Developed and released the 1.1 update
-Exhibited at PAX and met many fans
-Met Mr. Yasuhiro Wada, the creator of Harvest Moon
-Flew to the UK to visit Chucklefish and collect an industry award
-Built a decent computer and got a nice big desk (No more HP Pavilion propped on a Wii U box)
-Worked with Chucklefish to make the Console ports and localizations happen"
