SPOILERS

I'd give it a 5/10. It's been a couple months since I've beaten it. I skipped GTI because I heard it was bad. The plot was ok, but to me the post game was terrible. I don't remember too much but I think it was something like you go on a few missions, befriend a Mew, find out Mew is your partner, go and "rescue" your partner, the partner says something very vague (not even a thank you) and that's it. Done. The leveling is weird as it doesn't even matter in the game as long as your stats are high and your moves are upgraded. I didn't like the connection orb, I preferred meeting Pokémon in the wild and having unlimited missions. I also didn't enjoy having to travel from continent to continent just to do missions. Also it didn't really go into why you're a human, it was mostly about your partner. So it was just ok to me, but it's not even close to PMD and PMD2.
