To say that the Pokémon 'Let's Go' games are catering to the casual audience more than the core audience would be understating the matter. The game has only the original 151 Pokémon, removes wild battles, and now Serebii has determined yet another change in the formula for Let's Go.
After playing the game earlier today, Serebii has determined that both abilities and held items are absent. This is yet another change that may upset the more dedicated fans. Interestingly, Serebii has confirmed that IVs and EVs are still present in some form, despite being a far more complicated mechanic.
