I've just finished re-playing Gold on my GameBoy Advance and I started wondering, which games do you need to Catch 'em all?
I mean, you could get Black 2 and start Wi-Fi trading, but it won't be very entertaining per se.
If you were to get all the Pokémon games to the date, obviously you'd be able to do it, but it'd be very expensive.
Which is the minimum quantity of games you need? And number of consoles?
