Since we're discussing general aesthetics (mostly), I thought I'd throw my two-penneth into the mix.
- Definitely changing weather conditions on planets, if only limited to 'story' planets. It can definitely be done in Frostbite, as those who play BF4 know from Paracel Storm, so I'd like to see dynamically shifting weather, as having something like the Mars sandstorm actually hit whilst you were still faffing about outside would be incredible!
- Truly alien environments. Something that is far removed from our Terran norms, with appropriate flora and fauna. I expect some places to fall within our norms, as it's easier to do things on Terran-like planets, but some diverse biomes would be incredible, and add to the sense of exploration in new frontiers! A bit like these shots:
- Proper material shaders that make the environments feel more real. I've played a bit of DAI (got bored for some reason and haven't been back yet), and it looked incredible. Hopefully they can make cloth look like cloth, metal like metal, and so on as that did on Ultra. One problem the previous ME games had was that the materials all looked pretty much the same, with a vaguely plastic look to them. Say what you like about Arkham Knight, but I loved the way that the player character was rendered. Below are a couple of shots of me playing as the Knight (modding FTW!), and it's easy to see what's meant to be metal, fabric, leather, etc.
ROTTR also has beautiful texturing and materials, as others have mentioned, with non-plastic looking skin that really adds to immersion, and gives everything that verisimilitude of an actual physical environment.
- In a similar vein, have a good character creation system. DAI was a start (though I lost count of the amount of times I played through the opening sequence to see if my character passed muster before canning it and starting again). As others have mentioned, the Mirror from the Normandy was a prime place to put in a character creator in-game, so we could change facial features after the fact, and is one example of an acceptable gameplay/story segregation. I'm one of those that bangs on about EVE having a fantastic CC (shame WiS still isn't implemented), and I've seen the YouTube vids of Black Desert Online, which look amazing.
- Also, one aesthetic thing I liked from another game was the minimalist UI from Dead Space. It felt more immersive that what you saw is also what the protagonist saw, and the life & stasis meters on the back were physical items on the suit that everyone in the game world could see, as well as the ammo counter on the side of the weapon you were using. And who can forget the Zero-G and vacuum sequences? I hope BW have taken some hints from this series as to how to do Zero-G (i.e. floating around with small cold gas jets to move you).
- And finally, for now anyway, I really enjoyed the look of the ICS from the sadly cancelled Tiberium. It was a great-looking bit of kit, and I would really like to be able to get something like it for MEA. Also, it had a great way to differentiate males and females around the chets, without resorting to 'boob armour'.
But, these are just a few thoughts I had.
