This is pretty much what I do every Generation of Pokemon. At first, it started out with Pokemon Pearl Version. Once I beat the game, I got bored of it and drifted out of Pokemon for some time before coming back about 2 months later for Diamond Version due to losing Pearl. After beating the game a second time, I played quite a bit more than my 1st time but eventually drifted away once again. Eventually, I found the older games and started playing them, refueling my interest in Pokemon once again. Once I heard about the release of Pokemon Platinum, I went out and got it and beat it again. Thankfully though, this time there was a Battle Frontier, which was one thing I missed from Emerald. This time, I stayed with Pokemon for a good 2 years at least before drifting away AGAIN. Finally, Pokemon SoulSilver was released, and I was back again, pleased with the new refinments in the game like the GB Sounds. I played with this game for about 4 months before drifting away from Pokemon once more and expanding my gaming horizons beyond it.

Currently, I have drifted away from the Pokemon games but plan on coming back to get White Version. I just can't wait!:D
