I think it makes sense in context:
- Development started in 2018, as a PS4 exclusive (PS4 being Atlus' target platform at the time)
- It was the team's first game in Unity
- The game was low scoped and low budget
- At a certain point Microsoft started paying for ports to their systems, and it went fully multiplatform
- A Switch version may or may not have been explored; if it was, it probably did not run well. People get defensive at this part, so I'm going to spend some time elaborating:
- Unity is an extremely inefficient and resource intensive engine at the best of times
- Unity does not run great on Switch (there are, obviously, exceptions)
- This game is not a well optimized game (look at the DF breakdown of it)
- This team is obviously not too technically talented, especially with the last few points in consideration
- It was still possible to get it working on Switch, obviously. Some finagling and it would have happened. But the team clearly lacked the knowhow (this barely holds it together on the PS4, and that's the target system for the game to begin with)
- It was still possible to get it working on Switch, by outsourcing it, but there's obviously very little budget that was allocated to the game to begin with, so that option went out the window
- It was still possible to get it on Switch, perhaps as a late port. But the game got a critical cold shoulder, and also bombed, so who would it be for?
- All those circumstances conspired to keep it from Switch
SH2 aside, every single Atlus release in the last four years either has a Switch version, or is a Switch exclusive - TMS#FE Encore (Switch port of a Nintendo exclusive game), Catherine Full Body (Switch port), 13 Sentinels (Switch port), Persona 5 Strikers (Switch multiplat release), SMT3 Nocturne HD (Switch multiplat release), SMTV (Switch exclusive), Persona 5 Royal (Switch port), Persona 4 Golden (Switch port), Persona 3 Portable (Switch port), Etrian Odyssey Origins (Switch console exclusive). I just don't get where the idea that Atlus' Switch support is lacking comes from at this point, they have released more games on the Switch since 2020 than they have for any other platform. They have more Switch exclusives since 2020 than they have PlayStation exclusives.
Yes, Soul Hackers 2 missed the Switch, but there is a circumstantial explanation for it that is unique to it, and the game itself sucked anyway, so why that is used as a sticking point, I don't get.
