Massive improvement in visuals and details over OIAL, and that was already a good game. One thing to keep in mind is that the game takes place in the same universe as OIAL, which means mystical elements are confirmed to exist in the world from the beginning, so don't expect it to be pure sci-fi.
All the characters are likeable and possess their own flavour. So far, the protagonist seems unreasonably blessed in his ability and relationships, but much of the plot so far has hinted that he's an unknowing beneficiary of some dark shit, so not just a Mary Sue character, and some level of wish fulfillment is reasonable in the genre. So far the choices are pretty much only differentiated in how ideal they are, but the plot may split into two meaningfully different routes based on how he reacts to whatever the "truth" is.
There are many references to Greek mythology in the game, although mostly just names where understanding is optional, which is nice because my personality as a theorist has lead me to actually learn some as a side effect. The plot itself isn't that complicated or hard to understand, but there's a lot of hints and symbolism to keep a curious mind active in trying to figure out what's actually going on before it's properly revealed. Although the game feels like it's still in the opening stages overall, there's actually a lot of content already, and it's content with a lot of variety because of the game's "virtual multiverse" setting.
I was sad I couldn't talk about it on the discord, but it's understandable to limit it to patrons if there were shenanigans. Unfortunately, all my money isn't really my own and I can't spend it freely in good conscience.
