Gone Home was a very pleasant surprise. To clarify, I know the game has a lot of positive hype, but when reading reviews and reactions prior to purchasing I noticed a lot of backlash about Gone Home being championed by certain groups for its message rather than the game itself (and that reviewers were supposedly giving it glowing reviews because of this and blah blah).
I would fall into the latter group regarding why I think it has received so much critical acclaim.
That's not to say I didn't enjoy the game...I certainly did, but I don't think it deserved anything close to the "masterpiece" status so many critics fell all over themselves to give it.
Respective of the genre, I think something like "Dear Esther" is far more worthy of those accolades, and in this case, I think the game itself probably would have been received better if critics would have shown a bit more objectivity in the reviews. Instead, half of them come off as pretentious pseudo-progressives, which is pretty transparent (and annoying at this point) and has the effect of bringing out the cynic in a lot of folks.
IMO, a good game, and worth the sale price.
