Nah 2 basically has everything 1 has.
Only if you want to complete your PokeDex
Thanks for answering all my questions. Gold/Silver include all the original Pokemon from Red and Blue right? I do want to complete my Pokedex if possible, but I missed out on Genesect and whatever other event-only Pokemon have been released. I'm not really into competitive battling so just beating the games and filling up the Pokedex is my goal.
