Lets see The one from SWSH was a joke... although not as much of a joke as Sun/Moon.. Its been so long since I played x/y... Didn't play bw1 or bw2... Barely remember Diamond and don't remember silver that much besides that annoying red haired thief so its down to team rocket or team aqua. My $$$ is on Team Aqua.
edit: But DP is being re-released at end of year, so I very well might be replaying diamond before that happens just to see how the remake measures up.
