Of course I enjoyed the games, but I wouldn't ask for anything from them back to future generations.
Sometimes I play my Blue and I think "oh how could I survive all this time without running shoes?", "Wow only one Special stat that's retarded", "why there is so much grinding I'm fucking tired of this". Some people say that they love them because of the simplicity, but I believe Pokémon got much better when it started to get complex. I love that challenging feeling the newer games gives me, beating a Generation II onward (specially Generation IV and V) game feels much more rewarding than beating a Generation I game.
The Bike Theme is great, it's my favorite Bike Theme of all, but somehow makes me feel sad, and Pokémon Mansion Theme makes my body dance (I don't understand why people say is creepy). Favorite songs of Generation I and frankly Generation III remakes of those are bad and doesn't make them justice.
And the characters too. I love Crystal, love Hilda, etc. but I have never been so attached to any other characters as much as I'm attached to Red, Green and Blue (even thought Blue didn't even make it to the games). And it's been years and Misty it's still my favorite Gym Leader but that's probably the anime fault.
Somehow my game's batteries are still alive.
