Red Dead Redemption.
I'm sorry, I love a lot of Westerns, mainly spaghetti Westerns, which this game cleverly nods to a few times, but I can't for the life of me figure out why people think this game is so good. The world is so huge, but there is by and largely a whole lot of nothing to do outside of the main story. My options for minigames are herding cattle, playing poker, and throwing horseshoes (which is actually pretty fun). That's about all I found worth doing outside of the main storyline. Hunting challenges are too boring, and I didn't really feel like finding a guide to look up where to find them. The plant collecting challenges are hysterically awful. Who's terrible idea was this? How is collecting plants fun in the slightest?
I'd also like to point out how the middle of the story is complete, 100% filler. The entire Mexico plotline is pointless until the last mission where you find who you came down there for. Since Rockstar prides itself on making these huge sandboxes, how about making a game where half the story isn't an utter waste of time?
I'm not saying it's a bad game, but Rockstar remain in my eyes, the single most overrated developers of this generation. Nothing they've done now is worth even putting in the same sentence as San Andreas in my opinion.
