The second generation is the "first" generation that I remember the most. I played Blue when it first came out, but Silver was the game that I remember waiting for, reading all the hype on it, getting excited, actually getting the game, and playing it for months.
This is why I'm looking forward to the remakes, because I want to relive that time.
Also, Johto is my favorite region, and I want the chance to re-explore it without the worry of the internal battery going dead. The updated graphics are a plus, as well.
