Not sure if this counts as technically I didn't pay for it, but F-15 Strike Eagle for the Sega Genesis was pretty miserable. Extremely poor frame rate, really difficult to tell what anything is thanks to the chunky visuals (pilots parachuting out of planes are literally represented by a straight line), it's just not a good game at all. I feel bad for asking for it from my parents.
As for a game I bought myself, I'm beginning to think it's Switch Sports. It's got only a handful of games, one of which you can't play multiplayer at all without two controllers, and every game controls worse than either of the Wii Sports games, which is truly baffling. It's still got a little bit of fun as a multiplayer game since you're all in the same boat of god awful controls, but that's about it.
