So the point of the OP is that Pokemon is bad because Nintendo releases 2 versions? How many people, besides die-hard fans, actually buy both versions? The games are meant to be played socially; you're supposed to trade with your friends to catch all Pokemon, not buy both versions yourself. :/ And no-one's claiming the 2 versions differ greatly.
It's not like Nintendo are saying 'hey, here are 2 TOTALLY different games that are NOTHING alike! You have to buy both!' In fact, quite the opposite; throughout the years they've always been stressing the multiplayer aspects of Pokemon, and encouraging players to play together with friends who own the other version to complete the experience.
From the OFFICIAL Pokemon website: 'To obtain every Pokémon, you'll need to trade with other players!' - http://www.pokemonxy.com/en-us/pokemon_101/game_exclusive/
OP fail, but nice try.
