I'm really conflicted about supporting this. On the one hand, it looks amazing, and the fact it's not being developed by GameFreak is (sadly) a point in its favour. On the other hand, I still don't want to support the Pokemon Company after the near annualization of the main series and the drop in quality thereafter, good spinoffs can't fix shit what the main series refuses to acknowledge its problems.
You could always just support the individual games you like and not support the individual games you don't like.
Also, Let's Go was innovative and fun for me. The game after that was Sw/Sh, which was the first normal new Pokemon game we got since Sun/Moon in 2016, three years prior. Let's go was different so it doesn't count as an annualization, nor does Ultra Sun/Moon because they were just enhanced, different perspective stories of Sun/Moon. The DLC also doesn't count as a full game. So if we just get Snap/Remake and Diamomd/Pearl this year, it will be at least two years between Sw/Sh and the next full game, and I suspect we will get a Let's Go game in 2022 and the next full game in 2023 personally, perhaps we ben as a Switch 2 launch title with a decent effort put into it.
Now, that all being said, I do think the quality of Sw/Sh and especially of Sun/Moon was lacking and I do wish they would do better, but then again maybe the simplification has contributed towards sustained success with today's kids.
Perhaps the market is ready for a company to make a Pokemon clone that's aimed at teenagers and adults. Maybe even Nintendo would do it with Level 5 or some NA subsidiary?
