Tomb Raider: Angel of Darkness - The gameplay mechanics are fucked, and the controls are so shitty it's downright unplayable - but I can't help enjoying the darker story and the feel that the game was going for. If it hadn't been rushed to market, I truly think it could've been one of the best Tomb Raider games ever.
The Sims 4 - Apparently, a lot of people consider it one of the worst games in the series, if not THE worst, but I actually think it's quite high up there due to its better graphics, pretty fantastic customization, and how involved the gameplay itself is. Granted, it has a LOT of problems, like the shitty optimization and the fact that basic game features like pools and TODDLERS were originally omitted, but I still think it's a far better game than Sims 3.
Smash 4 - This one may be a bit dicier, since it is, at the end of the day, still a game under the Smash title, but I often hear this game cited as the worst Smash game for being too easy. I personally don't really care about that, since I think the game's main purpose is to be playable and fun, which it was. It also fixed a lot of the problems from Brawl (NO MORE TRIPPING, thank god), and had way cleaner graphics and less clunky movements which streamlined the gameplay. It's my second favorite game in the Smash series, next to Smash Ultimate.
