Borderlands 1 was shit. I have a feeling those who liked it, had co-op partners the entire time.
Couldn't get into Borderlands 1. Couldn't get into Borderlands 2. The people I know who rave about it are either super casual gamers who are ok with just hammering away at bullet sponges and looking up where to get the good stuff orrrrrrrrr they're numbercrunchy types who are totally fine with the bullshit jrpg "big numbers" gameplay.
I found it all really boring and the story overrated. I'll give the writers credit for unique and interesting characters, but that didn't keep me around and I don't know what's supposed to be so fun about those games.
I think Skyrim is one of the most overrated games of all time and it's a sin that it's done so well and will encourage further garbage from Bethesda.
Doom 2016, while great, is way overrated. I think it's a ton of fun but holy shit people shut the fuck up. I've been dubious about Doom Eternal being as good as people say because of how hyped people get for Doom 2016.
The Batman Arkham games or whatever. I only played one and watched a friend play others sporadically. Those games are "your brain no work, just push button and collect glowy things" games.
GTA V. Nothing else to say. GTA Online has killed GTA for me.
Metro Last Light isn't even fun.
The entire Assassin's Creed series is shit.
As for games people said are overrated. Thief is fine and while the game wasn't originally supposed to be a stealth game, it sure as shit is not a fighting game and that's very clear. It's still one of the best stealth games ever made which is both amazing and depressing.
Half Life 2 is fine and holds up very well imo. Just don't go expecting iron sights and super smooth gunplay same as jumping back to HL1.
