I'll be honest, I wouldn't take advice from someone who 1) Hasn't made an MMORGP and only played them for "20 years" 2) who can't even make an interesting video that grasps someone's attention for more than 2 minutes. 3) There's a reason that so many of the MMO's that he's listed don't have more than 1 million active subscribers. 4) Some of the MMO's he listed barely even have a 6/10 on Steam.
It's pretty clear that majority of his preference is based on older MMO's because, clearly they have "not gotten better" because "modern MMORPG's SUCK" regardless of sales numbers showing the opposite of this claim. Let's not forget this guy has played MMO's since they were first released. In 20 years he only has an opinion on what he likes about old MMORPG's and how to fix them (make them sell less) That's what this game was based on as well. Which is why it's hard to get behind a MMO in 2021 when it's inspired by 2005 MMO's.
I also played MMO's a lot in my childhood, and the reasons this guy details as "improvements" are the exact reasons I quit them for a good 10 years before getting into this one. Which one of us is correct? Well there's a reason the MMO's that I like sell well.
