I have been amazed of what Eric has created single-handedly already, and am so pleased he's doing something new! Stardew Valley is a prime example of what I want in modern games and so often find lacking. No microtransactions, single-player-friendly, not graphic-intensive. Not every game needs to or should be Stardew Valley, of course, but there's not enough Stardew Valleys out there.
Few of us are as talented as Eric is, but I wish more of us tried a little harder to create what we wish existed, and not fall into the trap of what's popular. To bastardize legend, "If I were not [me], I wish I were [ConcernedApe]."
