I'm assuming VI is X and Y? To be honest, I don't really like them much, and haven't finished them. A big part of this could just be my current mental state or "growing out of it", though. I think some of the changes they made made it annoyingly "casual" and stuff... Though I've not looked into the mechanics, but the friendship thing or whatever it was just... Annoyed me.
I do like the fact that they didn't add many new Pokemon though, I REALLY like that. And the battles are really pretty and the animations are nice and stuff! But that leads me into another problem... It's just so SLOW. If I remember rightly, it took quite a while to load up battles. And the animations (which I want to watch because they are very nice) just take ages to complete. Because of that I just put the game down and decided it isn't worth wasting time with... Sigh.
I should pick the game back up, and give it another go. Or make my own mon game or something.
Yeah, it is definitely true that they added some pointless things. But that's true of practically every generation. The nice thing is you can basically choose to either ignore the potentially-helpful-but-'casual' things for challenge or nostalgia or whatever reason or use them as you see fit. It allows for more variability in how you want to play the game, which I like. One nice thing about Pokemon games in general, really, is that you can always tweak the difficulty to whatever you want by adding restrictions (Nuzlocke, etc.). The animation time is perhaps a problem, but I haven't had any issues with lag or loading times except for Horde Battles (though that might be partly because I'm not using the 3D).
Regardless, you should make your own mon game since Miasmon (or Beast Signer or whatever variation thereof) doesn't appear to be coming out any time soon. I would play it.
