Two starters is awesome. Can't wait to roll out Squirtile and Fennekin in my team of niceness.
Although, I cannot help but wonder about other pokémon: I run my team by a strict "One type per slot" basis. I can't see many people going out to catch the same type of pokémon you start off with.
I'm not saying we shouldn't give love to the starter trio's; it would be nice to have a choice between non-starters to begin with- or at least a different trio of types.
Nevertheless, I do quite like the new mega-forms(I never thought I'd say that in relation to Pokémon), with blastoise's trio of cannons easily being my favourite mega. I'm quite happy with this addition, to be honest.
Lastly, the obligatory cloud addition that the future generation of gaming will incorporate. A grand idea, but I've never completely trusted cloud storage. I only use it for files that I've already backed up. Meh- that's just my opinion.
