Pokemon Let's Go Eevee
Indeed. Everything CK just said about the game is valid, but I just finished it too so I might as well give my rundown.
I will very much miss the roaming pokemon. It's adorable to watching them wander about the map even if it isn't super complicated. I won't miss the catching. It is harmless for 90% of the game, ditching random encounters for just straight catch mechanics makes some sense tying into Pokémon Go. For the first half, it's great honestly. Reduces the tedium quite a bit since it still gives you XP. But it catches up with the game. Most status movesets become pointless on most pokemon because you don't need them for wild catches. And endgame/aftergame you're just tossing a dozen Ultra Balls for each catch and it doesn't feel like berries do much to help, so it becomes actively annoying and flips to an exercise in tedium. The sole exception to this is the rare encounters like Snorlax and the legendaries, you have to fight and KO them first before going into the catch mechanic- all with a 5 minute time limit. This worked honestly! But I don't want to get frustrated throwing Ultra Balls at an Electrodude for 5 min.
While as CK noted, the game is super duper easy, the mechanics updates really bring the charm back to the RBY formula. It's a great nostalgia trip.
Team:
Partner Eevee: What CK said. I found myself running Psychic and Dark, with the third slot for whatever gym or dungeon I needed. Ice for E4 Dragonslaying. The only move I kept after the move tutor became available was Swift for neutral damage. They also make sure Eevee is goddamn adorable.
Victreebel: Almost all Grass and Bugs are Poison, one of those Gen1 quirks, so the Poison side not much use, but for a Grass attacker worked very well. Power Whip is pretty great.
Nidoqueen: Works quite well as a Ground attacker once she evolves, even if she relies on non-STAB attacks mostly until she evolves. Have wanted to eventually use one of Queen or King, so it was good to finally have the chance. MVP of mid-late game since I gave it the Mt. Moon Moon Stone, but didn't get to do much in E4.
Clefable: It does take a bit to really notice the tankiness (after it evolves, an issue since the second Moon Stone is a bit into the game), but it does its job. Very few Steel types to threaten it and non-STAB damage generally isn't a worry, so you're only looking out for Poison damage, which only really gets threatening in late game. Moonblast is pretty strong and works as a Dragon slayer.
Raichu: Very useful, even if there aren't quite as many Water types in play still plenty of Flying as well. Considering I didn't use a Psychic type and ran it on Eevee, maybe I should have gotten the Alolan Raichu, but it would've been a huge level hit so I just skipped it. I committed all my Rare Candies to...
Omastar: Of course I'm running Lord Helix. As CK mentioned its great that it joins at a much better level and evolves immediately, but I still had to invest a decent amount of Rare Candies into it to catch it up to the rest of my team. Mostly used it as a Water attacker honestly, I didn't need to use the Rock side much.
