Also red is cooler. It has charmander on the cartridge
I feel like a total ass by saying this, but no it doesn't. It obiously has Charizard on the cartridge. You knowm the evolution of Charmeleon, which is the evolution of Charmander, which is the Pokémon you were referring to... you %#$&ing $*%#^&(!@
Uhm.. I do know that you probably meant Charizard. Just sayin'...
IIRC, the base stats of the "blue exclusive" pokemon tend to be higher than those normally exclusive to red.
However, with the ditto glitch, you can get any of the 151 Pokemon at all.
Ingame, the main differences are the default colour schemes when played on a GBC/GBA, and in the introduction sequence.
In the intro sequence of Red, you see a Gengar fighting a Nidorino. In blue's intro, Nidorino is switched with a Jugglypuff. There's also a different order of Pokemon on the title screen (where you see the trainer)
Out of all the important stuff, such as game engine, and ingame events, the 2 games are 100% identical aside from a few altered encounter rates.
Where logic won't work - I will If you don't have 8 minute lag - you're not doing it right!!!
