It is probably doable, but I think you would be susceptible to burn-out (depending on your other job and general mental health too). Lots of phds areas in the US it is pretty common to have “duties”(teaching,TA,grading,tutoring), for a stipend and cover tuition, but in my experience that was generally less than 4 hrs a day. It will probably depend a lot on how quick and demanding the phd program is at your school. Maybe see if there is a way to get less hours or just do research while at work (if you think you can get away with it)? Waiting to see how the workload is doesn’t seem like a bad idea but I don’t know how inconvenient it would be for you to wait a few months. 6hrs of productive research sounds like a stretch anyways no matter what you are doing, but I don’t really know what your CS research “looks” like.
If you currently have this workload at a job plus doing a master’s I am not sure how much more work comparatively you would have compared to PhD(again this depends on a lot of specifics), and if that is comfortable you might do just fine(also generally research can be “easier” to do since it is more fun and you are motivated, hopefully, than basic class work in a masters etc. This also depends on specifics).
Infra Arcana(awesome, free, roguelike), trying out Super mario world rom hack - Nachos and fried oreos and jump 1/2.
I might get Hyper Demon at some point, it looks dope and enjoyed Devil Daggers. Might get steam Dwarf Fortress too(whenever I play the free version lose a week or two of my life, then don’t touch it for a year and starting to get the itch again). I have Final Fantasy Tactics on my list to play. Also sorta want to play a puzzle game, not sure which though–maybe actually finish Baba is You.
I don’t really pay attention to recent releases or keep up on that stuff, so nothing to say about 2023 games.
