'New' means what exactly? 'Great visual' - so I think good looking 3dcg (renders & models), good looking 2dcg also good?
Does type of game matter, VN is good? Does it matter who you're playing as (the son or the mother)?
Do you have a list of what m/s games you've already played & liked (so ppl can get an idea)?
(I suppose you could just edit your OP instead of giving answers to my questions in a new message - less clutter that way.)
(+ I see you're new here, so maybe Glossary: or "what the hell is this acronym?" A resource for noobs on F95zone is helpful (see the 'tags rules and list' link for tag explanations))
One suggestion I good make already is to have a look at
Ms.Denvers [PopDoggy]. I haven't played that myself yet, but it looks like it's a HQ production with great visuals, and I believe there is a m/s dynamic/storyline. You play as her.
And then an older VN (2019, but still in development):
Away from Home [vatosgames]. Lots of hot scenes, and a very long & intense scene with your mom at some point ;-) I found the game not as 'bad' looking as the screenshots may suggest. Anims are pretty good. More of a smutty game than Ms.Denvers though (say, type fuckfest)
Mom is
one of your LIs here. Your favorite, butt still attention is pretty much divided amongst all the LIs.
