There's very little chance of a Twine game--or any work of interactive fiction and its adjacent genres--winning a GOTY award from a mainstream gaming publication. There are a billion factors behind that, from the cultural primacy of visual sensation to the lack of critical and institutional familiarity with IF to the fact that games like these don't often find their ways into the play queues of people who don't seek them out. This isn't unique to games: You could've just as easily said "Okay, but are mumblecore/noise rock/comix good?"
So yes, they absolutely can be good, and my advice is to try them (and, hey, try some other experimental and independent games like those that Warp Door curates).
