This review is in response to the galaxy-brain take from Benjamin Kukkee below. Oblivion was released fifteen (15!!!) years ago. If you are comparing a 15 year old video game to a AAA title from 2021, that's on you, not the developer. That's like comparing a first gen Nokia 3310 to an iphone 12, and then complaining about how much the Nokia sucks. Technology has advanced exponentially. Duh.
It's obvious this person played the game for several minutes and rage quit because they weren't doing well. Lockpicking is laughably easy and you can buy lockpicks from the Thieves Giild (a quest line they obviously didn't do) or from a vendor who hangs out outside the Imperial City walls. You also literally find them everywhere with random loot? I never had a shortage on any of my playthroughs. The minigame to improve NPCs disposition toward you is also incredibly easy. And this business about an unreachable tower? I guarantee there is a path to it if you had the patience to find it. You think you discovered a bug that no one else has in 15 years? Not likely. Also, Bethesda has made quite a few games since 2006 and continues to do so. Unless you're writing this review from the distant past. In which case, buy Google Stock!
Oblivion has the reputation it does for a reason. Solid game play, awesome quests, and at the time of release beautiful graphics. (The graphics are potatoes by 2021 standards, but so is every game from 15 years ago. Go look at Tomb Raider Legend from the same year.) There are some unique mechanics too. I still wish they would bring back spellcrafting like we had in Oblivion. It was sorely missed in Skyrim by many of us. There are quest lines from Oblivion that still have an emotional impact on me. The first time I got to That Part of the Dark Brotherhood? Gut wrenching! The fate of Martin Septim? He was too good for this world. Does the game have flaws and glitches? You bet. So does every game. I wish folks could go back and play Oblivion when it was new so they could understand how great it was at the time. I replay occasionally for nostalgia (it's a comfort game) but I know it's dated as heck. So is Super Mario Bros. So are all the old gen games we go to great trouble to play on emulators and the like. Adjust your expectations and enjoy it for what it is. And when you see him, tell Uncle Sheo I sent you. :)
