Sure mate, i have no clue what your taste is and what have you played so i will give you my personal top 3 which is mostly finished or well known games and on the side a top 3 lesser known newer games. Keep in mind that for me when judging a game writing is top 1 for me, then visuals and last mechanics and everything else...
eternum Solid developer overall, awesome stories with great visuals (i would also put his previous work on my top 5
OiaL)
depraved-awakening Another solid dev with great creativity, if you care for visuals maybe start with
city-of-broken-dreamers which is his current work.
tales-from-the-unending-void or
now-&-then cant decide, the second one is finished but the 1st one is more story driven and caters to more varied fetishes.
That would be my top 3, now the lesser known tittles they are not totally unknown by any means but easy to miss for a non VN player...
above-the-clouds If this one was more advanced in development i would include it on my top 3, its imo by far the funniest game here. Worth trying if anything just for a good laugh!
elvensang Deep lore and awesome writing, wouldnt recommend to you atm because its a heavy reading. Instead i will mention
the-swordbearer which is also fantasy, a lot less darker and great small town feel good vibes.
For last will mention 2 good dating sims
fates-collide &
tune-in-to-the-show, they are both really well written with gorgeous visuals and reminds me the old times before the harem/incest overload when choices where important and it was all about meeting characters, dialogues, etc...
Your pc its better than mine so im sure you can run all of them with no problem, have a good one m8.
