I could say GTA V. I know it's sold 135 million. So, just for me personally. IGN gave it a 10/10 and even though I knew it's not my style of game, their review convinced me it was a must play so I ran out and bought it. It was Hilary Goldstein(?) on the review I'll always remember. A dude named Hilary.
Predictably barely played much and got bored....GTA is not my thing.
When I was a kid, maybe Sonic on Genesis. Rave reviews, but I bought it and didn't find it that great.
TBH my gaming history is like that, I'm very finicky, other than Destiny and SF2 I have never played just a ton, and rarely find games I actually do enjoy.
