So, time for that long post with my thoughts on this trailer, that I sort of promised yesterday.
First and foremost: Gen VII is real! To me, the games might as well have been announced yesterday. What we got in February was more of a "declaration of intention" to give us Gen VII. Until now, it just felt just as faraway as Gen VIII without anything concrete to build on. Now, however, we have actual stuff to look forward to. We won't just have any ol' adventure, we now know we're going to the tropics. While some may bemoan the fact that it means two tropical games in a row, I'm happy enough. If the same art team worked on ORAS and SuMo, they've already got a lot of practise with that setting before they even started work on Sun&Moon.
Trainer customisation is back, and I think it's here to stay. I don't think we've had distinct, expressive player characters since Gen IV or so, and the player character was always meant to be whatever the player wanted anyway. Or rather, it's meant to be you, so the trainer model is merely a placeholder design for most intents and purposes. Making it customisable just futhers that notion.
What we've seen of the region so far looks gorgeous. Actual terrain, vibrant foliage, and it seems like they've gone to some effort to integrate the buildings in the setting too. The (starting?) town we see in the trailer has buildings placed in an off-grid manner, set beautifully against the hillside, rather than the square-grid-plonked-on-a-field layout we've had in previous games. The seaside harbour street looks really good too, more like an actual town than a collection of random buildings. Seeing the shore line without 90-degree angles is also a huge plus. I think I'll give some further comments on the region in a separate post later, so as not to interrupt the flow of thoughts.
I also notice that the camera seems to be angled much lower than we've been used to previously. The games are transitioning from a distinct top-down perspective almost to third person, which gives us a much closer look at the landscape, and opens up possibilities for more scenic vistas or intricate little details. The overworld design of Pokémon has always been somewhat limited by hardware and software, but it seems like the designers are becoming more and more free to create something detailed and beautiful. We're now walking with the player character, rather than looking down on him from above. Gen VI experimented a bit with this, but I think this is much more polished and refined. Maybe not perfected yet, but much closer to what the designers are aiming for in the long run.
As for the new Pokémon, many other people have already provided comments better than I can. It seems like the creature designers are avoiding bipedal humanoid starters this time 'round, which makes sense since Kalos had all three starters turning humanoid by the end. Then again, humanoid designs have sprung from the most unlikely starting points before (Sewaddle, for instance), so I might be wrong. I feel surprisingly un-frustrated at the thought of Rowlet taking the Blaziken route, though. As for the legendaries, I agree with the general sentiment that the Moon legendary trumps the Sun one when it comes to originality.
All in all, I think they delivered a fine piece of promotional material in the end. It took them a while to show something concrete, but what we got certainly doesn't disappoint. I'm excited for Gen VII now, in a way I hadn't been until yesterday. My curiosity is poked, and I can't wait to find out more.
