My favorite game as a kid is this crap 

                                                     it f***ing SUCKS!!!!

I actually haven't come across a game I loved as kid and now hate. The closest thing is probably Star Fox: Adventures. Really liked is a kid but I played it recently and didn't like it as much, not hate, just didn't really enjoy it. 

Jackie Chan is awesome, apart from that i love every game ive played in my childhood

I don't much care for Mickey's Wild Adventure these days, but it was one of the earlier games I owned & played a lot.

jackie shan was AWFUL !! even as a kid i knew that!! haha mine would either be sims or pokemon. i dont hate them, but there just not appealing to adults, like at all. i just out grew them.

Well, trying to play hide and seek with your dogs is no where near as fun as it used to be...
Other than that, I can't think of any.

The only set that really comes to mind are the Harry Potter games, but that is partly because the games got progressively worse after the Prisoner of Azkaban.

I didn't really play many franchises when I was younger, the only I did was Halo and I'm still playing that.

Blast Corps...i still dont know if that games is awful or pure geniuse.

probably have to be pokemon. I was crazy about it from the years 8 - 12 even collecting all the toys, now I can't stand it.
