I am thinking about too get FireRed or LeafGreen but with 1 i shall choose some1 can help me with it? becouse i prefere the version where u can catch the mostly Pokemon...

Depends on what version you want and depending on which pokemon are in the version your going to choose.

i think firered cuz i have it and u can get a cute little jkjkjk

lol i will just read the guide thats better i think and look withs 1 is better in me eyes

Fire Red, just 'cause Growlithe is awesome, and Charizard's pose looks much cooler then Venusaur's pose on the box art.

Depends. I'm playing Leaf Green purely cus its closest to Blue, which I got first.

This page explains the differences in which Pokemon are avaible. The fact that Leaf has Misdreavus swayed me too

Firered because you can get scisor.

Well yeah Fire Red has syther or however he is spelled. I bought Leaf Green when it came out and I prefer it to Fire Red. Basically they're the same except for a few select pokemon they come with. Just look under the Dex to see which pokemon you will prefer.

my brother got leaf green and i got firered
my brother got ruby and sapphire i got emerald (off topic i know)

anyways leaf green has the almighty magmar,where firered has the famous scyther. growlithe, psyduck and scyther are the majors in fire red.
magmar, vulpix and slowpoke are the majors in leaf green
