I haven't had a truly "bad" gameplay experience in my opinion, but I had a rough time with Super Mario Sunshine.
The early game is all right, but I just had too hard of a time with the later, harder parts of the game, and I eventually gave up on it. Some of those places that make you lose FLUDD were ridiculously hard for me.
All things considered, I'm fairly certain I could handle SMS today, but I ended up selling it. Oh well...
Superman 64 or ET for Atari. I once played them to see how bad they were and I've never stopped regretting it. Of course, this is a gross over-exaggeration, but they were both pretty bad. Apparently they made ET in about 6 weeks to push it out before Christmas or something.
Any Call of Duty game.
I hated every single one I played.
In my oppinion it's just a game that keeps getting recycled every damn time with little difference.
And I think it's overrated.
They do keep getting recycled with little difference. I dislike every CoD game I've ever played except for Modern Warfare 2, for unknown reasons. As far as overrated goes, that isn't a factor in my liking of a game, but they ARE overrated.
To be honest, I don't truly hate a game to the bottom of my soul, every game has strengths and weaknesses, positives and negatives etc.
If I had to say the game I least enjoyed, it would have to be 'Shrek's Treasure Hunt' for the PS1. It was a dull item collecting game and I remember disliking it due to its repetitive structure which just involved collecting indiscriminate objects that had nothing to do with Shrek. I'm just going from memories though, it has been a long time since I have ventured down that dark tunnel of movie spin off games.
Seriously don't buy it, I was obviously a silly 6/7(/8?!) year old to think it had merit enough for my saved up british pounds.
I was also looking through the collection and I found my mom had bought 'Barbie Race And Ride' for £20! Big mistake is all I can say.
Any Chinese Wii/DS/PS3 clone with "60 games in 1 or 20 games in 1 etc" packs. Seriously.
When I was about 7, I bought a WHOLE CONSOLE for about £20 that literally was just clones of popular NES titles like balloon fight and Kid Icarus, just worse, and uglier. Played it once then never again. The discs you used were made of plastic and did not actually store data, but rather the diameter was measured to find out which pack of games you were playing. A waste of money, it was.
