I would say I am a purist to an extent ...
GEN1 holds a lot fo sentimentality, It gave the first concept of pokemon and sold it for soo many people
I have played later gens and didnt find that I wanted to play through them again
However I much prefer FireRed to the Original Red the updated graphics etc made it even more enjoyable
I also feel the amount of pokemon taht were added started getting a bit obscure..
In particular the legend/spirit/w.e pokemon and thing like the oen based on rubbish?
I did however enjoy Ruby quite a lot, and I like the viewpoint in black/white..
I'll always feel for me that the original is best, It was the seed that spawned so it cant be rivaled
But that doesnt mean i hate the rest of them.. haha
