I understand and agree to some of what you are saying however I would like to clarify one thing, I admitted to not playing the current iteration of SG not the former, I have played the pre rework of SG. By that definition I can clarify right now without having to have played the new updates ( i think I played the very first rework of SG a bit too after it got reworked ).
Just as you have described WiAB being a mess, let me just give you an idea what pre rework done by Ocean looked like. It was way worse than whatever WiAB is without adding the 0.6, to put simply, it was decent but did not hold a candle to it. To simply quote you " the remake was badly needed to elevate it to SG's level " you are correct that the current needs a rework to get on the level of visuals at the least ( in my case ) but now imagine the reverse in this case so you can understand where me and most people come from who were here before SG was even around in the first place.
Imagine having a decent game already than taking over a subpar project you was advising take that game and invest in it to improve it and than have new people ( for example like you and most current SG fans ) come and saying that SG is a much superior product and that he should focus on that instead of this one and use statistics of the SG in terms of patreon to justify why it should be happening, When before the SG updates WiAB was the lead in making money and was the superior product already. do you see where I am going on with this ? So while I understand what you mean in terms of support for SG taking the lead and as such it should be priority, all he would be doing is alienating those who were here in the first place already and second of all his support there only dwindled because he has not updated the game. So While I understand I disagree that his focus should be on SG, SG has at this point gotten enough attention and we from the WiAB have been waiting long enough.
I have never attacked Ocean or done anything negative towards him other than point out either facts from his actions or statements or given my opinions, And while I want him to bring out the best product I have been patient for a long time and like I said I am currently very much admitting I am a bit salty to see 2 updates in a row for SG instead of the promised 1 for 1 update.
EDIT: PS : Another reason I am also salty is because I have predicted how working on two games and having computers or better gpu won't do fuck all but hinder his production on WiAB let alone focus on two games at the same time, He has said while he understands where most of us come from with saying that, that would not be the case and here we are with 2 updates for SG and zero for WiAB and now with people trying to get him to focus on SG yes I am very much frustrated, I am not saying he lied but life happened however my point and prediction turned out to be a fact just like every other single one, I was hoping he would at the LEAST prove me wrong ONCE that is all.
