Among the inordinate number of truly superb games released in 2017 were some hotly-anticipated (by me, anyway) follow-ups to indie games of past years. Some were sequels. Others were sophomore efforts. Whichever the case, 2017 was a very good year for promising indie developers releasing something new after a couple years of silence (or, heck, three or four or five years of silence), and having that new release not disappoint. Below the fold are my six favorite releases that followed up on the promise of something a developer made before.
