Seems like we all overestimated The Ascent. Currently sitting at a 65 meta on Xbox (vs 74 on PC), and the lowest prediction we got was a 78 from Shaunodon, next lowest was a 79 from me. We also overpredicted on Last Stop, I thought it would review fairly well, since the last game by that dev team, Virginia, got an 80 meta on Xbox One, but Last Stop is currently sitting at meta's between 64 and 71 on various platforms, with a 64 on Xbox.
I've been playing The Ascent on Xbox and think it is okay enough. The PC score is more accurate to the quality of the game than the Xbox score.
