5th gen. RNG is better and more enjoyable but Pokemon from 4th are more valuable Imo (well, something like a shiny roamer is different, but you know what I mean :P). Imo :P
That's great! I have a Platinum that I should probably learn to RNG on, but I don't really feel like it :P The only things I'm missing out on are the Stationary Pokemoon, though. And I guess a few wild Pokemon.
