And then the Splinter Cell franchise shortly went off the rails, crashed and burned as soon as they decided that some of the most fundamental of those rules should just be abandoned, for the sake of basically more broad appeal via making the game easier.
Its honestly kind of shocking that someone has not just made an indie, more graphically simple version of some kind of melding of Splinter Cell and MGS core game mechanics, perhaps without the relatively costly voice acting and grandiose, superbly animated cutscenes.
Im waiting to live somewhere with an actual internet connection, and I am convinced I could put together a proof of concept build in UE 5 in 6 months, a comprehensive level.
Stealth Action games seem to be highly regarded and in great demand, but for some reason no one really makes them in 3d anymore, unless there are some hidden gems I've somehow not heard of.
PS: Assassins Creed doesnt count, the AI is braindead when it comes to stealth, takes turns attacking you... using modern terminology its just a 3d ARPG.
