New Vegas had a pretty buggy release. It was unfortunate that a common bug happened about 12 minutes from the start of the game, but the most damaging was a save file corrupting bug. These got fixed, but their presence marred the image of what should have been a shining example of what a game could be.
Black Ops is next up. It didn't even have good story, innovation, or level design to save it from its awful bugs. Hitbox errors, AI breakdowns, and other catastrophes were all the norm during gameplay, both in single and multiplayer. But the worst of all was the mess of netcode for multiplayer. Games were dropped constantly, lobbies had the consistency of half-ply toilet paper, and zombies was like an experiment in inebriated programming. Top on all the poorly balanced gameplay and the overall lack of attention to detail and you have one of the most terrible games I have ever played. I swear, Superman 64 had better designers than Black Ops.
See, Skyrim isn't the only thing I'm disappointed by.
