It's a weird year for most disappointing as games pretty much met expectations. The crew never expected The Order to be good, so I doubt that'll make the list. Evolve could, but once again I don't think the crew cared that much. Arkham Knight is one of the games that they were actually hyped for that they didn't super dig, and it's got all the PC problems. I could easily see it make the list.
The other game I can definitely see is Broken Age. Expectations were really high after the KS and people liked Act 1. From what little Brad talked about it, and my and general reactions, Act 2 was a definite let down. Could definitely see it making the list.
If we're saying The Order could make Most Disappointing, so could Mad Max. I think that has the same problems in terms of the list. No one really expected it to be great, so now that it's just OK, it's not really a disappointment.
