I don't like how painfully easy it is, and people whined about SM and USM being too handholdy.....
There are some features I like however that I hope stick.
1. Catchable starters; They aren't legendary Pokemon! Just let us catch them in the wild. I'm sure everyone's that watched the anime has wanted this.
2. Pokemon following you and you seeing the wild Pokemon. It's such a time savoir, especially if gen 8 does that thing SM did where the actual new Pokemon have 5% chance of appearing.... I play the new games to use new Pokemon, not spend a hour searching for them! I can just breed and use Bank but that's doing things the easy way, I like using Pokemon that I catch myself!
3. Gym rematches! Praise the gods above, I thought this feature was dead after DPP! I hope this returns, I really really do. The Elite Four should NOT be the only way to get EXP postgame!
And I loved Leaf's portrayal. I hope we see her and Blue again, Red.... no, just stop.... him showing up is pure fanservice. He's a blank canvass and boring. Blue and Green are fun characters with actual personality.
**** list:
1. Motion controls; Ugh.....
2. Endgame. After XY's Looker Plot, Episode Delta, Ultra Beasts, and Team Rainbow Rocket it is quite depressing having a "What now?" feeling after you've won, I get it's to appeal towards the gen wunners but at least FRLG had the Sevii Isles :/
3. "You must own Pokemon with an advantage!" "Hey, here's a way to beat Brock and Misty without even trying!"
4. Not-Gary; Can gen 8 please give us a Silver/Hugh/Gladion character as the main rival?
5. No Espeon, Umbreon, Crobat, Steelix...... you get the idea
Overall, this is probably the least amount of fun I've had with a new game since XY. At least XY didn't limit your fun and you had access to all the available 700 Pokemon at the time barring the unreleased events
